So, having used this for a number of days now (and read the documentation to learn properly and not miss anything), and having used many other photo editing software tools for many years, I would have to say this software is a mix of good and bad things.This software has some powerful tools, many of which work extremely well, but many not so great and need fine tuning and better options to control them, particularly the tools that are more unique to or done differently in Pixelmator Pro. For the most part the software seems bug free, which is really good and important, yet there are bugs in some very basic and important things, like being able to revert back to a previous version (which in general isn’t designed well and is lacking features, it is basically like using Time Machine). For example, I was doing a number of changes, and needed to revert back to my original photo (undo seems limited and would not do it, another not so good thing), but the options on the menu allow to revert back to previous saved versions, which I did, all the way back to the original, but I noticed after it displayed that it wasn’t quite the original. Seems the only way I could go back to the original was to close the image and re-open it again. Now maybe it had loaded the original, but left some enhancement setting turned on, I wondered about that too, but can’t be sure; either way, it would not go back to my original as I wanted.Some of the unique features/tools are quite interesting, and work well, but there is that dilemma of whether or not they should be a one-button no options simple thing to use (and you take-it or leave-it), or if there should be some controls to fine tune the results. I always prefer the latter, since you can always reset to defaults.Now to things I did not like. First, there is no history feature, so you cannot see a list of what you’ve done, and step back through changes or view before/after at different stages (though a few tools do offer a Preview button, but most don’t). To make this worse, it seems the Undo feature only works to a limited degree (not many levels), and changes seem to get locked in at some point, even without saving or doing anything that might suggest this should happen. The ‘Revert To’ features feels like it is an attempt to compensate for a lack of history or more undo levels, but it’s not so great, unless you make your own notes about what changes were made at what times.The overall interface is not very well thought out, though it can be customized to some degree. For example, things like having active/status info displayed on a single line that spreads across the entire width of the screen (so cursor position, colour under cursor, selection position, offset, etc), to just look at that info while working, your eyes are having to move and hunt back and forth across the whole width of the screen-wide info line, rather than having that info more intelligently in one small area. It also displayed needless screen wasting info like canvas size and number of bits of the image, not something you need to have permanently showing on the screen. The main tool control panel on the right does of course change if you select specific tools from the toolbar, but there are a very small number of tools on the toolbar, and there is no way on the tool control panel to change what tool/control is showing, you have to go through the text menus at the top of the screen (or memorize the shortcut keys, which appears to be how they work around this) to do that, and that is very inefficient.As far as those top/text menus go, they are extremely poorly thought out and not well organized, making finding things more a matter of memorizing rather than being logical or intuitive. For example, there are Image, Tools, Format and Arrange menus. Image contains obvious things like image/canvas size, colour profile/depth, but would you expect to find something like ‘ML Super Resolution’ there, and image enhancement button, or should it be under Tools along with all the other effects and things that alter the overall image? But even then, the Tools menu is a disaster, including everything from the selection controls, to image modifying tools (which are illogically split between this menu and the Format menu), to Zoom controls (yes, there are also other additional Zoom controls in the View menu too - should all Zoom controls be together in one menu, under View, not Tools?), to drawing creation tools, to an export command (yes, there are also other different export commands in the File menu too). And though selection tools are in the Tool menu, mask tools are in the Format menu. Colour adjusting tools are in the Tools menu, but there are also more colour adjustment tools in the Format menu. To make things even worse, some identical options/tools/commands appear on more than one menu, but most only appear on a single menu, with related tools/command split up and appearing on different menus. I think you get the idea, the menu system is simply horrible, one of the worst I’ve seen in any kind of software; it is like different people added things over time, without any thought about organizing, or even simply keeping related things together.The software seems fairly quick, but in a few areas slower than I expected (on a Mac mini M1), even the Export dialog has some long delay before it appears, making you think you didn’t click the button properly. And lacking basic and simple features like not even being able to see before/after (e.g. ‘ML Super Resolution’) in many (but not all) commands, without having to go back and forth with Undo/Redo, is not indicative of well thought out, consistent, serious photo editing software. It feels like many commands/features were independently designed and implemented by different people that are not following any kind common interface/feature design/guideline for the software, almost like you are using different programs that are just mashed together into
