[Interest] Qt 5 and filesystem

[Bo Thorsen]

Hi Stéphane,

Yes exactly, the problem is that QML is young. I expect that the 
capabilities will expand quite a lot over the coming years, and file 
handling is an obvious place for improvements. Qt (the C++ parts) had 
over 16 years to develop into the current system, QML is an infant 
compared to it.

If anyone on this list is looking for a hobby project to work on, this 
might be a great project for you. It's interesting, contained, and much 
needed. Those are three very good starting points for an OSS project.

Bo.
