jupyter interface vs. sagenb
I'm converting to jupyter from sagenb, and am having trouble finding equivalent interface shortcuts for a couple of features. (a) In sagenb, to get a new cell I can hit a +/wordballoon icon. In jupyter, do I have to go through the pulldown menu or is there some way to get a new cell by mousing inside the notebook? (b) In sagenb, there is a wysiwyg interface for the explanatory-text cells. In jupyter, I'm not finding one; I seem to have to code everything manually in markdown.
Am I missing something, or are those time-saving features gone?
Also: One feature I wanted that was not present in sagenb was the ability to delete output cells. (This is so I can make a lab notebook for a class without having to make a test copy and then copy/paste all the input cells to a fresh notebook.) Is that possible somehow in jupyter? I see that I can hide output cells, but it's not exactly the same.
Agreed that some of these things should be in Jupyter - and aren't.
