Sorry to necro an old thread, but this is something I keep on looking for and the various online responses to everyone asking this question always fall into the following categories:
- Why would you want that? (even though it's specified in the question)
- Just write a plugin, it should be easy! (if so, then why isn't there one already)
- Just don't synchronize your font settings (with no indication of how one could do that while still synchronizing everything else)
I use DropBox to synchronize my settings and sometimes I'll be using Sublime Text on a Windows machine and a Mac side-by-side and as I change the font size on one machine, it immediately changes on the other. This is really annoying.
If there were a way to just specify font-face settings on a per-platform basis, or have Preferences.sublime-settings have a thing like:
things would be sooooo much better.
