I've got some rare downtime and I thought I'd try my hand at making my own ribbon tabs. However, it looks like everything gets added as a "big" version of the tool, with no options for making them smaller or hiding the text like on some of the default tabs:
Custom:

Desired:


It might be nice to have some be bigger, but I really don't need any of them to be that large. It limits the number that I can put on each tab, too. Is there a way to define which size/style I want?
I also notice that the buttons that are small on the default tabs are, well, pixellated on mine, but I feel like there's not a way around that.
