It's my first day trying out kde in ubuntu. Earlier today I installed several hardware monitor themes in superkaramba but all but one (one that is too big for me) didn't show my cpu temps. So I uninstalled the temps themes. Now I've installed ktemperatures and wanted to try if they work but (dumb me) forgot how to install them (I can't by no means find that window again).
Thanks for any help.

Err..sorry, shame on me! There's a button 'download new stuff'.
