So irritating that even when I make a "planned mistake" to see if moving a lesson will adjust my plans properly, or deleting a linked lesson will also delete the information in the linked plan, and I fully intend to "undo" if it messes up, literally by the time I move my cursor from "delete" to "undo" it has disappeared. The people saying it lasts a few seconds, for me it is maybe one entire second. I have yet to catch this elusive undo button.

I agree. Thinking about not subscribing next year.

I need help understanding how these requests go back years and yet very little has been done to fix this problem. Perhaps it's time we stop paying for this site and use another online planner instead.

Where is the undo button? I wish this was more user friendly.

Lost an 2 weeks of math bumping and moving lessons. This is a problem as now I have incomplete lesson plans which affects my pay. Planbook.edu is waaaay better

I see that you have an "Undo" window popup after certain actions, but it only stays there for a few seconds. I have never noticed my mistake soon enough to utilize that elusive Undo! I just can't get the mouse to the "undo" link fast enough before it disappears. Please please please give us an UNDO button that stays there all the time, even if it only allows us to undo the last thing we did. PLEASE!

I need to undo a whole unit I copied in!

I just lost all my work by copying/pasting into the incorrect lesson. Just deleted hours of work in a few minutes... :(

Yes, please. We are having the issue of a teacher deleting lessons that someone else worked really ******* in the bank and then we can not get them back.

I had an error on planbook while moving something and now my plans are gone! It wasn't even my doing. The site had an error! Need to fix this. ASAP!

Yes, please!!! Plans are moved and inadvertently other plans get deleted. I am dealing with this, NOW:(

Same with undo overwrite. It's so frustrating. I accidentally clicked on the empty lesson to link...and lost ALL my work! :( By the time I realized the floating "undo" button was gone, and revision history wasn't helpful either. :(

Has any of you gotten a reply from the developers? I added an event and mistakenly deleted the whole year. I really would need to find another planbook to use if recovering old versions is not an option.

I need this most when I accidentally hit "All Events" instead of "Just this Event" after editing an event. It takes hours for me to fix and I've done it twice now. UGH!

By the time I realize I did something wrong, the undo option runs away from me.
Maybe the undo can be somewhere at the top of the screen.

A back button to undo a command!!

You should have a whole separate tab available for all the past days undo's instead of just the disappearing undo's.

Usually by the time that I figured out that I have messed up (ALWAYS because I realize I've been editing the wrong week) the green buttons have just disappeared.

A whole separate UNDO tab would be a smart way to ensure your mistakes don't total all your other work.

I WANT TO KNOW HOW WE UNDO SOMETHING WE HAVE DELETED BUT DIDNT MEAN TO AFTER WE COPIED AND PASTED?

Undo feature if we copy and paste something wrong, or delete something that we shouldn't have.

A recover or revert button that can recover accidentally deleted items.
