Based on the question: "I am used to work with different qpdfview sessions.
1/ qpdfview --unique --instance tex ... (3 files in the tex instance)
2/ qpdfview --unique --instance doc ... (7 files in the doc instance)
3/ qpdfview --unique --instance somethingelse ... (lots of files in the se instance)
After a while, if I want to reload the session 2 vith 7 files, I have to remember the instance name, and it's sometimes hard... So, I make it the hard way and look into the sqlite database but maybe one could add a tab somewhere whith all those instance names. That could allow us to easely reload all the files of one specific instance."
Solve the issue by implementing a command-line option "--choose-instance" to display a dialog containing a list of instance names that appear in the tabs table of qpdfview's SQLite database, so that the user can choose one or abort start-up of the program. The effect should be as if the instance name was specified directly using the "--instance" command-line option.
There is now a branch implementing this available [1] and linked to this bug report. Please test and report your findings.
