when the [Generic] [Action with startup] option is set to [Resume Last Sessions] the tabs that were opened when you exited Poderosa are reopened when you launch Poderosa. Great!
It would be even better if Poderosa remembered the placement of the tabs and opened them in the same order they appeared in at shutdown.
for example, I literally have tabs named qa1, qa2, qa3, qa4, and qa5. I like to keep these in order.
seen on Poderosa Special version 5.7.5 (Nov 20, 2010) using SSH connections.
Note with earlier versions of Poderosa only one cygwin tab would be restored with this setting. I don't know if that issue still exists with the rewrite of the tab interface.
