Adding blocks more efficiently

Hi all!
Kirby Blocks are great to use and it is cool how they are extensible.
The only downside so far is in the editing workflow of the users: Adding a new block of content ist cumbersome, since it is tied to a modal opening.
It would be great to have a more efficient way to add blocks.
One way could be to add the block icons to the bar of the block.

Like so:

Is there a way to extend this without having to touch Kirby’s core?

I also saw there is some work going on with keyboard shortcuts, but the conversations seem to focus on sorting blocks.
Is adding blocks also planned?
Is there a possibility to add custom Shortcuts without having to touch the core?

Thanks a lot!
