If I may suggest, re-ordering the selections, so the proper sequence is … sequential…
IE, change the script order so its 1 - 2 - 3
and maybe put in a hint that vacuum is probably not needed after doing 1,2,3 (or 1,4,3 currently).
1 check > 2 repair > 3 reindex
4 vacuum (not necessary after re-index)
I realize this is an advanced tool, but you are going to get non-advanced users trying to use it… might as well make it as simple as as 1,2,3 … 
thank you and everyone for their efforts!
