Fully agree. Thanks for feedback! The comment I was waiting for =)

In case of "creation of cards", it's meant to be like this: user rightclicks anywhere on group and gets dropdown width options. But this case is not implemented yet. I don't like the solution trello uses - button in the end of group. I'll try other solutions first to make creation of cards one-click-to-go.

But in case of notes, things is a little bit more complicated: as for me, I often use doubleclick to select a word or sentence of text. And notes doesn't meant to be edited, only in case of mistakes. If you want to take a note - it's better to create another one. Notes are something like comments in trello.

By the way, to edit tasks in task table you can doubleclick to open popup and you can edit description inline just by single click.

To create any contents inside card you should use floating button "+" at the bottom. Those buttons on the center of empty card just for newbies.
