Please give merged file a new layer/file name

[skyper]

Salut

Please give the layer after merging to osm files a new layer/file name. Right now the name is the same you merged to. If you load the origanal file, you can not distinguish between them (same name) and you can exidently overwrite it, too.

Thanks skyper

I don't think it is a good idea to make it standard behavior to change the layer name every time some data is merged into it. The best option you have now is to do Save As. You can also create a new layer and then merge both of your layers into that one.

The layer context menu already offers to rename the layer. The Rename layer dialog should probably get a checkbox that, when checked, causes the layer to forget its file association.

Another possibility might be to implement a new "Merge into new layer" action that merges all selected layers into a new one and thus combining the steps mentioned above into one command.

Sounds all good for me. My biggest concern is that if you save after a layer-merge, you can accidently overwrite a file by just saving it. I do not care how this is prohibite but right now you are not warned at all. Maybe a warning that you are overwriting the file would do it.

Why is the merge operation so different to you from any other edit you do to a layer? Do you want a warning like "The data has changed. Saving it will change the file on disk. Do you really want to continue?"

I can not undo a merge and right now there are quite a lot of bugs with merges. It happend to me yesterday, that I overwrote a file, luckily I had the original still open and I knew which one of the two files with the same name the original one was. So I could save the original one again.

(In [2901]) new button in LayerListDialog: Duplicate Layer
This creates a duplicate of the selected layer without a file association
see #4440

That will work for me and I do not have to load the original one again, too.

Nice solution.
Thanks
