Feedback from Waldir

The reason I added a delay to the one with the plus button is so that translators won't get distracted if they happen to hover the text without intending to add a term. I could shave off 100–200ms off of it though, if you think that's better? (The current delay is 500ms for the blue outline to appear and another 500ms for the plus to appear).

500ms is definitely too slow IMO. Especially when combined back-to-back to make it a full 1s of delay. (Why not show the plus sign at the same time?)

Perhaps if one could have per-language lists of stop words, the gadget could offer a way to add those by the translator so they won't be highlighted in the future. This might prevent the distraction effect.
