For the Bookmarks widget for Plasma you can now select which folder to use as base menu:
So you can set up a few Bookmarks widgets for your most needed groups of bookmarks. In a row on a panel, or for your different activities, or whatever you want to do.
Also will the tooltip of the Bookmarks widget be set to the name, the icon and the description of the folder. And even better, this data will be automatically updated if you change any of these in the global bookmark editor, like fixing a typo. Even in the settings dialog above the folder data will be updated. Thanks to the nice KBookmark* classes in kdelibs this all was quickly added.
For compile instructions see the link at the begin. Compiles also against KDE DP 4.3.
BTW: If you live in or around Dresden in Germany and want to have some fun and gather some experience running the Linux-Info-Tag Dresden autumn of next year, now is your time to get up and in contact!
Attracted by virtual constructs

Send per PM.
Nice! One comment on the UI: I think it would be more obvious what to do if the folder name was the caption of the button. Like this:
like this: “Folder: [X Linux-Info-Tag Dresden]”
instead of: “Folder: X Linux-Info-Tag Dresden [X]”
where X denotes an icon, and brackets denote the extent of the button.
Good idea, thanks. I had been looking into putting the icon and the label into a frame, but your idea is even better, adding the remove of visual noise and the reduction of space needed. Will commit that tonight.
What are the chances of getting this to work with delicious, and more generally allowing a user to select delicious, rather than a local file, as the place to store their bookmarks?
Seems very in keeping with the thrust of KDE SC 4.
No idea about the chances. Should be possible, as the interface to the bookmarks system is rather abstract. But I won’t do it, as I have no need and lots of other stuff on my plate.
Just found http://techbase.kde.org/Projects/PIM/Akonadi/Bookmarks, so the answer is: perhaps one day. Hoped that helped you 😉
Can I get a PM for the color theme too? 😉
Sure. Sent.
