Does the author of MO check this for suggestions? If so, may I suggest adding the ability to make text bigger? If this already exists (or has some other way to do it) I'd be appreciative if someone could tell me.
For people asking about stability and such, I got about 125 mods running on MO a2 right now and so far as I can tell everyone is working and loaded. Personally I use the bInvalidateOlderFiles=1, and that took care of previous issues I had with texture mods not loading.
MO, both the 1.3.x and the a 2.x series, make use of stylesheets to configure the UI elements. Currently MO a2 has two stylesheets which you could edit to adjust the font sizes.
The actual details are not fully ducumented but conform to QT standards and a number of modders have already created different styles that you might look at to see how to change the font metrics.
(one proviso here is most of them where created for a previous QT version and there may be slight variations with some keywords)
