We could try to do it together and maybe even make a video (stream) of
implementation process :)

Hi Peter
I wanted to ask about Bloc:
Thanks for your interest :)
1) how stable is the API? e.g. if some overhaul changes to unify/whatever
are planned
Api itself is in "final" state, however naming might be improved (changed
with or without depreciations). But don't worry user-side api is already in
a very good shape, at least from our perspective :)
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)
Exactly :) Lines are just bloc elements as anything else: buttons, text
images. They can be linear, can be arcs or bezier curves (both quadratic or
cubic). Default canvas used for rendering in Bloc (SpartaCanvas) has very
good support of vector shapes and lines.
The idea for me is to make a simple mindmap
- elements with some text, icons, math
symbols inside
- connectors (non-straight lines) between elements
It is very doable. Please, don't forget that Bloc is a low level framework
that does not contain any widgets (existing ones will be deleted,
especially BlLine, BlText and BlTextElement). The only responsibility Bloc
has is to provide a basic infrastructure that does not put any constraints
on users. Which means that if you want to have a bezier line you have to
subclass BlElement, implement corresponding accessors for anchor points and
override drawPathOnSpartaCanvas: in order to display you line. You can
learn more about canvas by checking SpartaCanvas class comment and method
comments in 'api' protocol.
Layouts, alignment, transformations are part of bloc and are available to
all subclasses of BlElement.
Cheers,
Alex
