Hi Kunda,
I think it is better to post errors in GitHub repo. Otherwise we grow up the thread here.

BTW: I could finish the first alpha version of save and load workspace files to restore UI layout. But it supports currently only panels, like:
- order in dock
- expander state (normal, advanced, collapsed)
- dock state (docked, floating, hidden docked, hidden floating)
- position on screen for floating panels
Next Steps: save / load for docks
best,
Martin
