There was –again– a long time no update to deditor, this was caused by a bug in the ubuntu overlay-scrollbars which showed ugly grey bars over any editor using scite. The most popular editors were added to a blacklist and got regular scrollbars to fix the issue. But for deditor there also is a solution coming! In ubuntu Oneriric the overlay scrollbars are fixed and deditor should work fine! If you want to stick with natty there are certain workarounds which I’m not going to implement in the main code.
I will start development on deditor 0.3.1 as soon as oneiric is available.
I haven’t had the time to think about what shall be updated yet but the projects plugin will definitely get a revamp as it is not good enough in my opinion.
