Please try restore deleted command (rd keyboard shortcut). Hopefully this helps.

Absolutely need this. I just blew away a whole node with no way of recovering it. (Yes, I am aware of backups)

See changes through time, and allow to recover or undo certain changes.

Regarding recent changes notification - if you have a Checkvist PRO plan, you can subscribe for the recent changes in the list, and the e-mail with notifications about changes will be sent to you. More about notifications: https://checkvist.com/auth/help#notifications

I would like to use this feature to know when somebody whom I shared the list with has made changes.

Another vote for history, including the ability to restore metadata (creation date, etc.) from backup.

Hello Shankha Das,

Checkvist doesn't remove list items immediately, they can be restored in a case of accidental deletion (but currently only we can do it, so you should write e-mail about this).

Also, Checkvist provides backup, manual for free version and automatic in Checkvist PRO plan.

All of this won't substitute real multiple revision data storage, but it is something to avoid typical data loss (data removal).

Also, we plan to provide a 'trash bin' - so removed items could be restored within a day or so after removal. Please vote/watch this request: http://checkvist.uservoice.com/forums/2121-general/suggestions/5312958-a-trash-bin-to-store-deleted-items-temporarily

Thanks,
KIR

In my previous company, we had tried the Pro version, and just because of this issue, which led to a lot of data loss, CheckVist was rejected. I am a big fan, and looking forward to implement this in my new company, but wondering if this will be the bottleneck. Any updates or alternatives, or even a multiple undo.
One specific problem was one of the team members deleted multiple items, and realized it was the wrong list he was working on.

I agree. Particularly useful for teams. I rely on it a lot in Google Docs.

Having a history of modifications on each task would be incredible. 3 votes for that one!

Olli, thanks for the suggestion, but the main difficulty here is a to create a living infrastructure for task history (this is a lot of work).
When to create list snapshots is a secondary question, you approach could work as well.

A middle way in case preserving entire state (including version history for task contents) is too much work: only preserve when a task was created and list order any given time. So one could roughly see which tasks existed at a point of time though the original contents of a task may have been different originally.

@Aurelijus sorry to hear that :(. The only thing I could offer so far is to enable daily backups in Checkvist.

+1 just lost some info...

Yes I think this is essential to move to the next level of robustness, peace of mind to use in large operations as I plan to use Checkvist pretty soon. I'm betting three votes.

Yesterday, when pressing the delete key to remove a single entry from my list, the key suddenly got stuck. When I released it finally I had accidentally removed about 20 entries, some of them containing notes and sub entries. The undo function recovered only the last one, so it was a very painful data loss. So, please provide a way to (automatically) save and (manually) restore revisions.

Yes please! I just accidentally deleted two long lists, didn't realize it for a while and then couldn't get it back :(

+3 ;)

I think it's very important. Revisions would be great.
