[Pharo-dev] How ready is Bloc for a simple use-case?

Hi, I wanted to ask about Bloc: 1) how stable is the API? e.g. if some overhaul changes to unify/whatever are planned 2) I saw in the techtalk that you can align elements (to center, bottom, ...), however is that possible with lines? Lines have to rotate, morph shape, etc. 3) Are non-straight lines possible? (e.g. bezier, arc) The idea for me is to make a simple mindmap - elements with some text, icons, math symbols inside - connectors (non-straight lines) between elements To me (apart from the lines) it seems like it should be already doable. Also either my (Morphic) Pharo is really slow, or Bloc (in the video) is superfast (everything is happening instantly). Thanks, Peter
