I'm not sure if this is the right place to post this. First, let me say how much I LOVE Xournal. I use it to annotate PDFs on my laptop, without a pen/tablet. The only thing that I really need Xournal to have is the ability to draw (not recognize) shapes. Particularly rectangles, circles and arrows. Is there any possibility of adding this feature in the near future?
It's a good suggestion - for tablet users this is not very useful (the "recognizer" does the same thing more efficiently), but I do realize that with a mouse it's not easy to draw a circle well enough for the recognizer to understand it. Given that xournal++ is getting close to ready, I think the right thing to do will be to implement this in xournal++. (so: not immediately, sorry!)
