@bastianallgeier have you checked if this will also work with v6/develop given that we refactored the batch feature internally quite a bit there?

[bastianallgeier]

@distantnative it's only introducing the same batch prop. The logic is quite different and a lot more simple because we don't have to switch between modes.

Thanks for this fast feature addition! ❤️

Just a quick feedback on the UI:

I looked at the still image before playing the video and neither did I understand that the box in the upper right corner was a checkbox nor did I expect what it was related to. I actually was confused that it was releated to this feature at all. Yes, this is a common interface pattern for interactive tables but usually all checkboxes are aligned in a column in that case. In general, I think this needs labeled buttons and it needs separate buttons for both selecting and deselecting: with a few items selected, I might want to select or deselect all depending on the context.

@nilshoerrmann you are not wrong. Here's another version.

That looks very good. Thanks Bastian!

Just one small change I think would be safer.
