SUMMARY When we split a view, both children get 50% of the space. If we move the splitter handle, we can change that. It would be nice that, if we double click on the splitter handle, the split would go back to 50/50. ADDITIONAL INFORMATION Maybe this could be pushed down the stack, but that probably need that the developer provides a preferred or default size for the split.

Merged, will be fixed in 21.12. Thanks for the good idea!
Thanks for 'fixing' it so quick!
