I think it would be good to add a confirmation for deleting a meter. I intended to click on the Save icon, but accidentally hit the Delete icon without realizing it -- then wondered why that meter wasn't there anymore!
It would also be good to use the same terms for both the icons and the context menu. Compare
ICONS: New meter, Delete row(s)
MENU: Add new meter, Remove selection.

It would take some fairly significant code refactoring (as compared to the current code) but it's nothing hard or anything like that. I'll try to find the time to do it.
by revising my own suggestion to something like Ctrl+R instead, to fit with the other shortcuts Ctrl+N, Ctrl+S, and Ctrl+D (for example, one could save and refresh with the sequence Ctrl+S, Ctrl+R). Either way is fine, it's up to you skwire.
