I've got a few issues I'd like to report with scrolling:
First, as you scroll down a file with long lines of code, the bottom scrollbar will change sizes. It'd be great if this could always stay the maximum size for the file.
Sometimes scrolling horizontally gets stuck with about 10 pixels to spare on the left, making it impossible to see the first bit of text on a line
Holding down ctrl and using the scroll wheel should scroll the application horizontally.
As an option, it'd be nice to have a "soft limit" to the bottom of a page. I (and others) prefer to look in the middle of my screen while coding, and it can get annoying having to look down at the bottom to wrap up a document. It'd be great if you could continue scorlling until the last line of code appears as the first line in the scroll view.
One last tidbit, not scrolling related... In Windows 10, it's difficult to open your tab menu. There should be a way to easy toggle this, maybe a key combo or maybe even an option to always show tabs on the screen, similar to touch IE.
