Interesting idea. I'll open a ticket and bring it to the table internally.
I know it's really crazy and probably not much demand, so I'll understand if the developers laugh out loud. :)
I just realized I could do this with the command line functionality. I can't "package" the credentials, but I can still make a dead simple "double click, get results" solution.
I've recently started playing with the DBVisualizer Variables for parameterized queries. There are lots of queries I run multiple times a day, so this is very convenient. What would take it to the next level is if I could "compile" and export these to an executable. It could include the connection information and credentials (encrypted). I could then distribute these to the helpdesk or management. The EXE would contain enough of DBVis code to run the query and display the results in a simple output pane, perhaps even include the amazing visualization options.
Again, I know it's insane, but thought I'd mention it just for funsies :)
