Undo deletion

[claell]

Currently it is pretty easy to delete a note accidentally. A confirmation question would avoid this.

Better than a confirmation would be an undo function (a message at the top of the app that hides after ~5 sec.)

I think it can be discussed, whether this is really better than a question.
Personally I never liked the approach of an undo function, I prefer preventing an unwanted action rather than offering an option to revert it later.

However this approach is used on many other sites and might be easier to integrate into the current UI.

In addition, @jancborchardt considered to put the delete button in a 3-dot-menu, see #38. This would reduce the likelihood to hit the button by accident.

We should definitely go with undo, as is also planned for the server and other apps. See the main issue at nextcloud/server#3216 and cc @ChristophWurst who worked on an implementation.

I just deleted a set of notes by accident...

[jancborchardt]

@waeltken can you open a separate issue and provide further info?

(Also just removed some comments related to the Android app which were separate from this topic.)

There is a CSS style for implementing this, available since NC12:
