1. The way you can add drum hits is to use the amount knob. It will try to add hits where it makes sense in a musical way. Further, you can copy or move the hits from one drum to another (if you, for example, want what the tom 3 is playing to be played on the floor tom) by using copy/cut/paste found on the right click menu on each drum.
If you want to add hits on an exact position you should (as you have done) record them, or drag the MIDI to your host and manually edit it.
2. EZdrummer 2’s windows is not resizable.
3. Keyboard shortcuts have been discussed a lot in the past, but the short answer is that hosts don’t let keyboard shortcuts to be used in plugins.
4. Lengthen MIDI blocks is only possible by copying them, not in the way Logic and Garageband does it.
When we design the programs we discuss these kinds of questions and solutions for months (and sometimes years), and trust me on this one – features that seems easy to just add to the product never are 
We are, however, constantly updating our products and we try to fulfill our customers needs so keep posting questions/ideas!

Henrik, thanks for the reply. This helped immensely.
It seems like I’ve owned EZDrummer for years but have only recently started using it in a more purposeful way. I commend what you all did with the move to EZDrummer 2. You took a good product and made it even better. In every way!
My questions are based on my experience with other software (and sometimes in other industries) and my work flow. Sometimes the obvious is too obvious. And sometimes it’s not. 
Thanks again.
