Multi Find: Search, Highlight, Explore

Seems very broken for me. For starters, from a convenience standpoint, there doesn't seem to be a way to "search" with the keyboard, since pressing enter jumps to a new line, I have to manually click the previous/next arrows to actually go to the found results. There's also no way to make it match default search behavior when it comes to closing and opening it. It either remembers your last search forever even after you close the window, even sticking through multiple tabs and forever highlighting words until you manually delete them, or it automatically deletes what you searched only after you close and reopen the window. The regular search disappears when you close the search bar, but still remembers the last thing you searched when you reopen it. Then, the colors for the highlight are always be very dull, no matter what I choose on the settings. On a functional note, it seems to randomly add those scroll bar arrows when first loading pages, often disappearing after a second but sometimes they don't and just stick there forever, even with nothing searched at all. Even worse, sometimes those arrows appear inside other containers of the page (like in a video) instead of only on the very edge. Finally, after messing around with it for a while it just... stopped working. It currently doesn't find anything at all, even after removing and re-adding the extension, closing and reopening the windows, etc.

Great app, but is there a way to remove the context menu line? I'm a fan of minimalism and try to clean up the context menu.
