Hello,

You don't need to apply to fork, it's open source you entitled to just
go ahead and do so.
Please send us a link to your repository so we can keep up-to-date
with each others work.

But to address your individual points:

 - 1. Tablet Mode Support: We have incorporated support for the UKUI
tablet mode, which differs from the existing tablet mode mechanism in
KWin.

Can you expand on what's different. I think we can improve on our
tablet mode, so if you have ideas I'm interested in hearing them.

 - 2. Virtual Keyboard
 On wayland or X?

 - 3. Custom Protocols: To fulfill the application requirements in the
UKUI environment, we have added or modified certain protocols, such as
the blur effect with gradual intensity changes.
If you do use custom protocols can you ensure they have a separate
interface name so we don't get any runtime collisions in applications.

 - 6. Dependency Management:
Out of curiosity which dependencies were the most problematic? There
has been a move in kwin to remove some parts.

 - 7. X11 Support: We require continued support for X11 and plan to
develop new features to ensure flexibility and compatibility of UKUI
across various systems.

There are lots of issues on Wayland, but long term it is the path
we'll all end up on. I suggest trying to fight upstream for whatever
needs fixing now, so that it can get fixed in the long term.

Good luck with your project, please do keep in contact, potentially we
can end up back in sync one day.

David
