Hello,
I kinda like the K9Call dialling solution,
except with portrait desktop in CSSU, it rotates to landscape, and half the widget is cut off.
I believe it is abandoned - in the K9Call announcement thread there are requests like this one, but no response, and they're old, too.

I'm starting this thread to find out how difficult (or easy) it would be to make this adaptation, and maybe even get some help with doing it myself.
Not being a programmer, I naively think it should require changing maybe a dozen lines of code or so, since e.g. tinkering with transitions also is only about adjusting several values in transitions.ini, right?
OR can single desktop widgets be blacklisted to not rotate?
What do you think?
