[Enhancement] Change album's Top Right menu behavior when selecting some pictures

[mkaraki]

I think almost all application change behavior of top right menu when files are selected.
For example, Google Photo will make option to add to album, delete and download options when some pictures selected.

But, Lychee won't change behavior. So I have to right click on selected pictures and select action.

I think changing options when selecting makes more easy to use UI.

Thanks.
