Problem Description

When a pane is split horizontically resulting in only two panes next to each other, the user would like to move the split of the two panes exactly in the middle of the window.

What steps reproduce the problem?

1. Open a file
2. Split horizontally
3. Move the pane seperator left and right

What is the expected output? What do you see instead?

User would like to move the pane split exactly to the middle of the window. This is very hard to do with mouse or touch pad to move to the exact middle, pixelwise. A small bump/threshold when moving the pane seperator in the middle of the window will allow the user to do this.

Offer this only when the full width of the screen has only one (top level) split (two panes). Additionally, this can also be implemented for a single (top level) vertical split. Here the middle of the available vertical space for the top-level main pane should be used, not the height of the window.

Hi @PanderMusubi thank you for the feedback! So, as a quick idea, maybe you would like some sort of action that you could trigger that would divide the available space between the splitted editors equally?

What do you think about something like this @spyder-ide/core-developers ?

Note: maybe QSplitter.setSizes (https://doc.qt.io/qt-5/qsplitter.html#setSizes) could be useful for something like this

[PanderMusubi]

Yea, that is correct. Implementation I leave go to the core developers.
