I like (and I will use) the small splitter icons, but for a new user, they may not even know it’s available. They almost blend in too much. Maybe make them more like a small button? Like put a box around each? I really don’t like the box idea but I’m just trying to find a way to make them a little more noticable.
Suggestion for an enhancement. I like how the dash “-” will reset the spit to the middle. Maybe add something like an “O” button to reset the split to where it was. Like if someone wants the split to be higher than the middle, so they can see more of the grid. They want it here all the time. Then, they want to se the whole grid, they would click on “^” to do this. That’s great. Now they want the split back to where they had it. They would have to center it first, “-”, then drag it back up. This is probably more practical on the split from the Column listing. Where it defaults to is a good location. But if you use the “>” to view the grid all the way across, there is no way to get it back to where it was without dragging it.
Kind of hard to explain in a message. I hope it makes sense.
