I have no objections to implementing a context menu. Other than that I am rather swamped at the moment. Who knew there were going to be so many feature requests/bugs just for the spell checker.
I currently have the following on my spell checker todo list:
1) Improve the goto next occurrence algorithm to ensure it only goes to matches in correct places ... see DrChiper's bug report (This is a big one, going froma parsed XML tree to a location in raw text accurately is far from easy)
2) Add an import word list into user dictionary tool
3) create a context menu
4) Investigate roger64's suggestion about elisions in French
I think I have already implemented everything else in this thread that was asked for, apart from a couple of things that I dont agree are good ideas.
