The work is proceeding, I wish I had more time, these weeks have been plenty of relax and I was able to get back to Oblivion as much as I wanted. Soon I won't be able to do so, I hope to finish this.
Everything is working smoothly, constantly testing with both controller and MKB.
...and I was tempted to use small fonts because they look pretty but in the end it's plenty of UI around making use of small fonts (and even too small). The fonts won't be huge but not tiny either.
And in the end I'll avoid adding fonts through script extender, sadly. It perfectly works and it runs once only, for the entire game session, so it would be ideal, though even setting the script to immediately start I don't like to risk to open the interface and the fonts aren't loaded, unfortunately it's not just about how fast it can run on seconds, frames is the wild factor and it varies too much. Hell, even in my own game, sometimes the fonts immediately show and sometimes it takes 2-3 seconds for them to appear, not ideal. Too bad.
