Right now once you save a workbook, that's it. If you (or someone else with edit access) changes a canvas, deletes a calc or messes up a filter and saves, there's no easy way to get back to how it was. The options are digging out an old .dva export if you happened to take one, or asking an admin about a snapshot, which brings back a lot more than one workbook.
It would be really useful to have a simple version history on each workbook, something like:
- Keep the last few saved versions automatically (say the last 10, or the last 30 days)
- Show who saved each version and when
- Let you open an old version read only to have a look
- Restore it, or save it as a copy, if you need it back
This would make shared workbooks a lot less nerve wracking, especially when a few people are working on the same one. It'd also save admins from restoring a whole snapshot just because one workbook got broken.
