I know, you've got many important things to do, but i think it would be nice if you could take a further look on your AppButton:
It looks pretty different as the original appbutton from office does. I took a screenshot in which you can see the Office-AppButton, your one (KryptonRibbonAppButton) and an AppButton from the DevExpress-RibbonControl. As you can see, the DevExpress-one looks nearly as the original does.
To be fair - the DevExpress-Ribbon is much more expensive as the Krypton one and (as far as I know) the DevExpress-Ribbon renders itself with predefined images (it's a real performance-killer). So you may probably not be able to draw a aquivalent button with your GDI-technique (btw: I'm happy you use an other technique as DevExpress does ;).
Anyway ... what do you think? Is it possible to adapt the original appbutton in the KryptonRibbon?
Maximize a KryptonForm with an AppButton. If you play a little bit with hover- and presseffects on the AppButton, you can (at least I can) see an unattractive drawing-delay. First, the lower part of the button ist drawn, then the upper rest follows.
May that be the effect by splitting the AppButton into 2 parts (the upper part on the form-border)?
At the moment there is a massive focus-problem if you click the AppButton. There are no hovereffects in the appearing popupmenu (I think this will be solved in the 2.7-release (ApplicationMenus))
Thanks a lot,
