Remember window size and position
The default window size allows me to see exactly 2 elements and the "Extension Updates Ready" bar at the bottom. To scroll through the list and find what I'm looking for today is ridiculous even if I can see generous 3.5 list elements after I began scrolling. It would help to see 8-10 elements by default. I also never want to have this window centered but on the left half of my screen because I a) open an extension's settings dialog or b) its webpage likely on the right half of my screen.
Remembering the window size and position would be awesome. Thank you.
