I create date-based hierarchical albums / folders for all my images according to the following scheme: ~/Pictures/Digikam/YYYY/MM.DD_Description_of_album

Just like in Animal Farm, all albums are equal, but some are more equal than others. ;-) I would like to visually highlight some albums (e.g. vacations, special trips, etc. - about 10% of my collection) among all my daily life children's playground and experimental images so they are easier to spot in the tree view. I use 16x16 icons so album thumbnails are not an option. 

Would it be possible to assign font color (just color, maybe bold/italic, not font or size!) to the album names in the left side tree view? Or maybe (even better) assign it to the album categories? This way I could set all vacation picture albums red/bold and all nature shootings green, etc. and highlight new albums just by assigning a category. Colors could be set in the settings, there is already a categories editor.

The same, by the way, would be applicable to the tags tree. There are tags I use all the time, a highlighting option would be great here.

Or maybe there is even a better idea to highlight certain albums?

Thank you!
