I wonder if it is possible to implement a search box which can do one or more of the following:
It could do so by highlighting the device icon in some way or by having an list populated into the log window for example.
I have used nmap to sample the open ports on all of my devices, listing the results per device in the notes window, so the search function would need to be able to parse the notes as well as all the other metadata.
you can see from the attached image that my map is fairly complicated (from my novice point of view, at least) and hence finding things can be tricky.
I have a similar idea on the back burner, there's some unfinished "compact view" code that would present the map as a tree-list so you could use it sidebar-style (like a friends list in a chat app) - adding search to that is a great idea.
"Tree view" - that is a superb idea!
