Know what you mean, would probably be a worthwhile feature request to make on the bug tracker.

You can change the zone size by dragging the border with the mouse while you are in the editing mode.

Edit: so drag to 1/3 and 2/3 roughly, split the bigger field again.

I see you figured it out. Will add an explanation to my post as well, if you hadn’t deleted your reply I would have answered that instead. :)

You have to hold the Shift key while moving a window for it to snap into the tiles you set up. If you just move them normally they have a different snapping behaviour like what you described.

Edit: So as the deleted reply was probably asking, this is how it works in full. If you have the KDE Plasma desktop environment after a certain version (I wanna say 5.6-ish?) you can do the following:

1. Press Windows+T, or as we Linux nerds like to call it Meta+T, to configure your “tiling zones” on your monitors.
2. Hold Shift+LeftClick on the title bar of a window to move them into the “tiling zones” you set up.

Discoverability on this sucks (as much of the Plasma desktop does) but it’s a pretty cool feature.
