some feedback from bigsur/m1

[nsklaus]

so i can confirm it works for me on bigsur, apple m1 system. i was able to access and modify the *.car files. that's very nice, i could remove the highcontrast white colour from the titlebars and toolbars. i replaced it with a light gray for now as a first step (see attached screenshot below). many thanks for making this possible @alexzielenski & @jslegendre !

now, as you can see on the screenshot in the terminal i'm seeing a message asking me to report some sort of problem. i'm not sure what it is about, and it didn't prevent the app from working. but as being asked i do report it.

2020-12-14 02:09:35.553 ThemeEngine[1299:25479] WARNING: The SplitView is not layer-backed, but trying to use overlay sidebars.. implicitly layer-backing for now. Please file a radar against this app if you see this.

also, i noticed a tendency for themeengine to crash if i browse the list of 'elements' entries on the left a bit too fast. the steps to reproduce are: click on the first element in the list, wait 1 second then press down arrow key to switch to the next element in the list. repeat this to quickly browse down the list, and after 10 or so elements the app crash. the workaround is to browse more slowly, and save often.

and finally, i was able to drag and drop a bitmap from pixelmator into themeengine to replace an asset. that is nice, but, i was not able to do the opposite, that is: drag and drop an asset from themeengine to pixelmator (or anywhere else). it would be nice to be able to do that. drag and drop from themeengine to pixelmator, modify the asset and then drop it back into themeengine. so far only half of that do work (only import from and not export from).

update: some more progress on theming big sur: this is using some of the mohave files. i got back gray gradients and white backgrounds for toolbar buttons. works everywhere with safari too. looks much better now. unfortunately no progress on toolbars increased height since bigsur.
