Two missing things

This is a good addon, but there are two missing things which are the following:

The first thing:
the history of any tab in a saved session is not stored, so after opening a saved session and loading a tab I can not go backwards to the previous addresses that I visited before saving the session and closing the window of Firefox

this behaviour is not like what was in the great addon
Session Manager by Michael Kraft that was in before Firefox change to web extension addons

I mean the addon Session Manager by Michael Kraft that Sienori was inspired by, as he mentioned in section of About this extension

---------
The second thing:
Also the saved sessions do not save or keep the hierarchy that was created by addon of Tree Style Tab by Piro (piro_or)


I hope Sienori update Tab Session Manager with these two features
