Multiselect from objects/features are not supported yet

[harrywipperfuerth]

Currently it is not possible in ODIN to delete multiple objects in layer management at the same time.

Use case:

The user wants to "derive" his Bn situation from the Bde situation and wants to delete all objects that are not needed.

Here it would be advantageous if the user could select and then delete all these objects by means of "multiselect" (e.g. pressing the CTRL or SHIFT key).

This should also be possible in other areas (e.g. multiple selection of layers, projects, maps etc.).
