Useful, but...

Nice app, but the ads are really bothering me, and the current update removes the useful ability to detach the toolbars.
I cannot understand why the developer does not sell Sketchpad as a standalone app. I dont want the other abilities Fastfinga provides, I just want Sketchpad without ads and with detachable toolbars!
