--Working with transparent layers and channels (compared with PS) is clunky.
--Too much duplication of buttons and window tabs; there are like four ways of exiting the program from the same place (window toolbar, tool pallette toolbar, WM exit, right-click tool panel, etc.)
--Weird script/filter difference (why are there both? why do some destroy undo history and others not?)
--No great selection tools (color matching, fuzzy matching, etc. compared to PS).
--Really really obnoxious "Save as..." which directs you to export for using non-xcf files (and it'll even chide you about that, when it's obvious what you want to do).
--Thousands of other miscellaneous gripes and grumbles.
Background: I'm a long time GIMP user. I've tried Photoshop in the past and hated it's way of doing things too - Corel Draw seemed to make most sense to me.
Anyway the new pedantic approach to saving/exporting seems to be pretty unfriendly - like you say it chides you, you go to save and GIMP says "n-uh, you can only save in XCF; what you want is to 'export' to a new format". Argh!
Whilst it's correct that you're exporting, there's no need for the duplication between save/export other than to indicate to the user that some formats will lose information.
Yep. It's one thing to simply have a "Save as..." dialog that only lists .xcf--then I have to figure out to use export instead and all is well.
But, to have that dialog box somehow actually say "Aha, we knew you were looking for those other formats, go here instead!" pretty much shows that the developers know what the user wants to do and are maliciously putting a roadblock in their way. It's smug and overbearing and quite annoying.
