I was messing around with some visual filters, typing in the morph codes and what-not, and then I right clicked a word in the ESV and chose "morph" and did a search....then I copied the morph code from the search to the visual filter box...a little bit of work...
I thought it would be great to have a right-click option that was something like "send to visual filter" like it does for search...or even "add to existing visual filter" if one is opened.
