Isolate Layers in Drawings

[jimmyflash]

I would like to add possibility to quickly Isolate one or multiple Layer in a drawing (at last).

Very useful function when needed quickly select multiple lines or objects from the same layer.

Thanks!

Example of usage:
When only a specific hidden lines are needed to be shown in a view is required to show all of them 1st and later hide all the unnecessary lines.

It could be a huge number of hidden lines mixed with another lines and objects and could be tough to select them. With isolated layer "Hidden" is possibble to select them quickly.
