Yup, I had someone print off Excel sheets, manually highlight and write in corrections, and them bring the pages over to my desk to have me fix them in the file.
I also once had the city reject a report I submitted because the width of the columns in the Excel file were different from the previous year and they wanted to print it all off on one page.
I have somewhere in the neighborhood of 300 mods installed for Rimworld. The in-game mod management system is pretty basic and simply does not cut it. Definitely interested in more management options.
