Update: I just submitted v1.13 which allows you to choose a default behavior for "Restore Session" in the addon options

Thanks for the review. Yes I will continue development.

As far as I know it is not currently possible to open the bookmarks sidebar or the bookmark window programmatically. I was hoping for a simple solution like that as well.

I am planning to add some configurable options, a default behavior for "Restore Session" is a great idea for that, I will definitely add that.
