Tomasz (and also Thomas), looks like you really worked on the issues I wrote down into the comments section of package version 1.10.2 ...

Now there is a bugtracker link, the toolbars show up as expected and also the UI is much cleaner than before. No need for my special keymap with a fullscreen key on my N900. Now I have changed from 1.8.3 to 1.10.* in extras-devel at last.

Well, the LP solvers glpk and lp_solve are still missing (as they seem to be external dependencies since some versions ago), but who wants to solve LPs on a mobile device anyway!

Keep up the good work!
