I have enabled save dialogous status and rememver window geometry. It still does not arrange the whole screen like it was closed. Pretty annoying and really destroying the workflow.

Iam using the dockable behaviour and iam on windows 10 using inkscape 1.0.1

Are the dialogs floating or docked? 

Are they all visible, or are some hidden?

Docked. Neither the order or which dialogs were pinned to the right are preserved.
Left as it is if i close and the right if i open inkscape again.

This might be resolved in the next release. A bit of work going on in the docked dialogs.

Thank you! I will use the development version then.
