Themes has been updated (solving issue #690), now that libclearlooks has been compiled for the Windows platform (to be downloaded in the dependancies folder of the FTP site)

A new checkbox has been added in the preference window to switch to a "slim" version of the selected theme, for low resolution screens
Curves now uses the theme colors too (was hard to see before with dark themes)
Themes has been named with this convention (of mine, yes) :
[Background ligthness]-[background color]-[Selected items color].gtkrc
Only themes with .gtkrc suffix are now displayed in the combo box

rtdata/themes/slim
