minor enhancement

LP version : 0.9.3.114

I think this crafting progress tree dialog is wonderful for finding critical path of bulky crafting task.
And it zooms and pans very nicely but I have a suggest.

Most of time, player may need not to be aware of what's going on around, so it will be better the dialog takes larger portion of the game screen.

TBH i totally forgot how to zoom it in XD

But honestly id like an "Enlarge" button as well.
