Re: A Question about Wizard Load Times
I'm hardly a pro at this, but I like option 1 better. I tend to keep my custom controls in the project directory to make it a little easier on SCC to keep everything together. That said, I don't have any super-flexible QControls that I need to inherit from, so if you DO inherit from non-base Qcontrols frequently it could be nicer to have them in the list. Option 2 does seem like more work to implement but for my personal use-case I don't think it would be too helpful.
Maybe an Option 3 would be to have the Load from Path auto-populate to the QSI/QControls/QControl Classes directory? It would be like, 2 more clicks to get to your general-purpose QControls than having them in the tree.
