Gui Editor for Char-style (or Layout editor): sponsorship project?

[Abdelrazak Younes]

Hello,

I've been asked privately by a generous anonymous donator how hard would 
it be to offer an easy way to select a text and to highlight it with a 
given color background or font.

My idea would be create a Char-style layout editor and to give access 
via a toolbar combo to the different char-styles avalaible. Right-now 
the supported char-style are not well known and that's a pity. We need 
to improve the discoverability of the feature.

The idea would be to create a sponsorship project for this feature (the 
generous donator would like to give 500€ for this feature). I would like 
to know if any of you is interested in the challenge and at what price.

Abdel.
