Add a 2nd Hypersearch results pane, and a control to select which to use in search dialog.
I sometimes need to do a big search on all source files in my project for a word. Then, when in each file that contains that word, search for some other word. Once I've worked in that file, I want to go back to the big all-project search and jump to the next file. For example, search for all occurrences of a class to find everywhere that the class is instanced. Within each file that creates an instance, hyper-search in that file for all references to the instance. Go to next file, wash, rinse, repeat.
Unfortunately, the big all-project search takes a very long time, so I don't really want to have to re-run it after the secondary searches. It would be nice if, like Dismal-Studio, jEdit offered a pair of HyperSearch Result panes that I could select between, so I could leave the big search open in pane1 while I do the sub-project searches in pane2, for example.
