Interesting. My idea was to not have to type = to evaluate, where enter would make the happen automatically. As we know <tab> is a way out of a container without evaluation.
Places for improvements
So I picked out a few quirks I've found while using MapleFlow 2022
1 - CRTL + SHIFT + arrow is supposed to move the container 1 pixel. Only works left and right, not up and down.
2 - Containers, when selected with the mouse, the button has to be held while pressing delete to delete. I mentioned earlier the container had to be moved slightly, but that is not necessary.
3- Horizontal alignment between math and text containers are slightly off. It looks like in the 2021 video on MapleFlow the alignment is ok so this could be a regression.
4 - Containers are always snapped to a grid point, they are not always placed exactly where you leave them.
5 - Can't just copy and paste a drawing from a Maple Canvas (As a side improvement for maple - to be able to draw an angle between two lines exactly at a specific angle, and also to be able to dimension lines to specific lengths)
