feat: add progressbar for tasklists (for each tasklist)

[seals187]

Hello there =),

Maybe add here (see printscreen) in the tasklists a progressbar too ?
It makes sense to see for each tasklist directly the progess via a taskbar, (and you can keep the 1/3 finished ! . this is
also a very good inidactor to see how moch subtasks need to be done...)

cheers
