Or what are the advantages of this new stuff, if you don't want to change somehting at the webgui yourself?
1. webgui itself, as you called it, changed. IMHO it's match better now
2. It's easy to have completely different looks: the way amuleweb "looks" is written in html+php and not
hardcoded in c++. Open it in your favorite html editor and change as you see fit.
3. Addition of new features (have you seen new stats page ?) is match easier
4. Other advantages that writing webpages in php have over writing in c++
