Multiple tab (session) opening
I want to upvote "Reopen PDFs Launched in previous sessions on Opening Acrobat/Reader".
Although you implemented reopen pdfs from last session, it would be INCREDIBLY useful to be able to save sessions. e.g. 5 specific pdfs regarding research on wastewater management could be saved as a session and 10 different pdfs (or some of the previous 5) as a session regarding Mn removal from water with an option to recall whichever I need when opening Acrobat. That would speed up a lot of people's workflow, especially those who have to jump through multiple topics with various materials.
