I suspect adding permanent spaces would make the alignment look funny. But I know there is a Copy event in Javascript… maybe I can do something with that. If so, would you prefer any features be added to the copy, like eliminating colors, or the dot in front of the row, or the Level headers? Or just leave it as-is (but with spaces)? And do you want spaces only for vocab? Or kanji and radicals, too?
I won’t making any promises about getting around to this, though. It may be a lot more work than the ‘hide’ thing was.
