Home / Some points that can be improved, maybe

Thanks a lot for this terrific PDF viewer. But here are several points that can be improved. I want to show you guys.
First.

According to this picture, we know that we can begin SumatraPDF on this page. I think it is great. But if I open some PDF, I will not come back to this page unless I close all the pdf I have opened before. I think if there is a way to go back to this page without closing all other documents.

Second.
Is it possible to personalize the Shortcut keys?

Third
Is it possible to give a Shortcut key to the favorites? if so, I don’t need to click many steps to collect the pages.

Here is just some advice. Thanks again for reading.

First
Can’t go back but using CTRL+N you can go forward to that page:

Add favorite is Ctrl+B(ookmark )

OR
Right Click page for context and its easy to add / remove or show.
