I've got a small patch that adds the ability to resize the font (& window) by using control+mousewheel... it's a pretty common accelerator in browsers & editors.
Should I just post it here, or where can I send it?
At first, there are Patches in Tracker.
At second, I've tried to do the same in the patch 1808723 Support Ctrl+Mouse Wheel. If you're interested, I'll be glad to compare our solutions [you can either send in your patch or just e-mail it to me]. Note: my patch applies to a quite old version, so you might need to do some conflict resolution.
Posted as patch #2808716
mine's pretty damn simple, and like the other one, the setting isn't persisted (but who would want that anyway)
