it's true, but maybe uncomfortable. After building a new tabble and choosing a colourname
And who forces you to choose a color name? Your doctor maybe?
I always have to put it also in the Colour-Tabble. Or is there another solution I can't see....

Previously you had to choose a color name. Now you have to choose the parent tabble. It's the same.
Also, remember that
tabbles are folders. In Microsoft Windows, if you create a new folder, it will be created as a child of the currenlty open folder. The same is true for tabbles. If you open a tabble, then, if you create a new tabble, it will automatically be put
inside the open tabble. So, no need to drag the new tabble into the correct container: it is already there.
We are trying to make tabbles as close as possible to common folders.
The non-zooming mode had the following advantage: I opened my explorer an the workspace of TABBLES (which was ordering the tabbles by himself), then I draw several files very quickly into their tabbles.
You were dragging files from Windows Explorer onto tabbles? So? You can do the same with the file-window. Just drag the files from Windows Explorer to the correct tabble in the sidebar of the file-window. (When you hover a parent tabble, it will expand if collapsed). Does this not seem equivalent to you?
