Re: Spreadsheet App for DM42

Wouldn't it make more sense to tie a spreadsheet to a matrix variable? Real matrices can hold six-character strings as well as numbers, so it sounds like that would do what you're looking for. It would basically be a fancier version of the Matrix Editor, showing multiple cells at once, instead of o...
