For example, if a folder contains a pom.xml file, the Maven project symbol appears. Maybe there also an extension point in the Windows standard dial...

I have started to use DevExpress LayoutControl a bit. It feels powerful but I don't get it as I want. I want to set a minwidth and minheight of components as you can't have a dialog real small and it still look good.

Can I stop this from happening? ...
