Merge (selection) into a new layer

[anonymous]

What steps will reproduce the problem?

1. Select any object.
2. Choose "Merge selection"

What is the expected result?

When there is only one data layer, a useful enhancement would be to ask a user "Would you like the selection to be merged into a new layer?" and provide "Yes" and "No" buttons. "No" could be the default, but "Yes" would be appreciated because currently users have to create a new empty layer first, then make the source layer active again, and then do the desired merge. Likewise, when there are a number of data layers, having "New layer" as an option in the dropdown list of layers would be practical too.

What happens instead?

When there is only one data layer, message "There are no layers the source layer could be merged to." is shown with "Ok" button only.

Please provide any additional information below. Attach a screenshot if possible.

I miss this option for merge in general. Right now, I always need to clone my data layer to keep the original layers. This is really a pain when debugging merge/conflict problems.
