Hi, I've fallen just a little ill lately with most dreaded man-disease called The Cold and thus have not looked into the theme much(The Cold is leaving me today I can hope). You're more than welcome to help. If you have Photoshop and a good idea for the look of the buttons and just a bit of patience then feel free to mock up some. Let me know where you run into issues. Do you want to try pasting the graphics in yourself? It's by far the easiest to fiddle with it on your own on your own monitor resolution. Last time we spoke my monitor got half and half on me. One image on the right that was the full resolution and the one on the left was much smaller. The equivalent of the resolution I've been switching to for the purpose of seeing how well the buttons look. I had to reformat because of that o_o I guess using SwitchResX and Resolutionator at the same time wasn't profitable. Right now I have a virtual machine with High Sierra in it for the same purpose; seeing how the theme looks.
I sort of did figure out that the roll and lack of text can be stopped by; having a slightly smaller(height-wise) active pressed button state and have a exact same canvas and size on the inactive buttons(including the pressed-down states)
In my 'Tiger-love' theme experiment I got as far but completely screwed myself over by fiddling too darn much. Looked decent though.
Back to the theme and the help - despite having The Cold I'm not dead and can still produce stuff - the thing is the resolution of the monitor + the canvas size. In my latest rendition I though I had it all figured out. The Canvas for the Finder buttons must be 22x25 and all the way to the top and leave 1px at the bottom - then for the 2x: 1px at the top and sides and 2px at the bottom... when I did that it at seemed to work - but the buttons looked too blocky and tall.
Perhaps if we just give it more radius on the corners? The blocky look would go away - to a degree. But the height of the buttons would remain.
One of the reasons for the various delays and iterations is that whilst making the buttons less tall and following the scheme of doubling up on the pixels from the 1x graphics then Finder and Apps dislike that very much. Some Apps follow through and look the part - like probably the Finder - then apps like Calendar, Mail, 3party apps looks like ****'e.
Also, talking and working together in a forum makes for heavy delay.
Do you have access to another medium that is better suited for transferring files and generally be a little quicker than the forums? My preferences are; Facebook Messenger, Telegram and iMessage (with some e-mail that is assigned). Google Hangouts I have but rarely use and my friend who's an Google enthusiast has kind of gotten the hint that I'm not there as much. Is all.
Perhaps I can just setup a Shared Dropbox or Google Drive folder for this; That's something new for me.
