Hi guys, I use Snow Leopard and love it but my eyesight is getting worse and I'd like to install Mountain Lion for HiDPI. Enlarging everything on the screen 2x would be great. Before I switch, though, I have some issues that I haven't been able to find fixes for. I want to make Mission Control more like Tiger and Leopard Exposé. This is the biggest. I don't want tiny thumbnails with huge gaps between them. I don't want my desktop and spaces gobbling up space on top. I don't want my background scaling down and distracting me. I want nothing except my screen dimming softly and all my windows being tiled as big as they can go. And to see the window title when I hover over a window. Like this. Disable Versions. I want to do this globally and safely. I read of some Terminal command for Lion but it was deemed unstable (back then, in Lion). Re-enable holding a dock icon for app Exposé. I actually used this and I don't get why it was changed/removed. On top of the Exposé issues above, it's like Apple purposely did everything they could to make window management worse. Proper 'Save As' Behavior. I know "Apple put it back in Mountain Lion albeit hidden" but it is still half-assed. It saves the file under a new name but it also overwrites the original file. I want it to leave the original file untouched, as 'Save As' should. Aqua scrollbars and scrollbar arrows. It may be superficial but the rippling scrollbars have been my favorite visual in OS X for over 10 years and the gray everywhere is ugly as hell. Thanks in advance to any gurus/modders who can advise on any of this. Also, alternatively, if anyone knows of a HiDPI hack for Snow Leopard, I'll gladly take that instead. I've tried Quartz Debug but in SL it seems to be just a really buggy implementation of resolution independence, not stable or usable. Thanks.
