I found a well maintained framework that match all needs. See here: https://github.com/githubuser0xFFFF/Qt-Advanced-Docking-System Check latest status here to see it in action: Scribus-IndigoUI-Mockup

Experimental Qt Docking extension written for Scribus1.5>=

I decided to stop developing of IndigoDock as single project as seen on https://github.com/nitramr/indigoDock. My code doesn't fit well in current Scribus code base.

Now, I'm full focused on integration of IndigoDock in Scribus and all necessary optimizations and upgrades. In short words: I'm developing a special version of IndigoDock which fits perfectly in Scribus code base directly in the Scribus code. Later I will put back the improvements and useful upgrades to the original separate project that others can use it for their application.

Working Scribus Version which uses IndigoDock you can find here: https://github.com/nitramr/scribus-indigo

Currently I'm on restoring the panel and dock settings for workspace saving. And I'm on fixing some UX issues. But basic integration was successfully and the dock is usable. ;)

Thank you guys for waiting so long time for real results.

greets, @nitramr
