To be honest, i'm also doubt its usefulness for experts ;) My intent is to help anyone who feel difficult to remember the options for writing regex (i'm one of them, i refered a lot while writing the app, duh!). Also for those who are just getting their hands on writing regex (may attract them to regex, i hope!).

there's no option for qr// though. just m// and s///.

For the regex, insert string item 'ind', then create subregex with selection group, insert 'ex', create subregex, insert string item 'es' as group, with extra option 'not necessary', return to previous, insert item , return to previous, insert item, insert string 'ices', complete, return, group item. select 'i' at flag.

Yes,quite tedious. Consider this as an experiment. really need your help (and everyone else) for giving feedback. thanks.
