Objet selection mode menu colors and hidden meshes!

I will combines two ideas here because they are related to visibility.

When you change selection mode with TAB key, the text in the drop down menu should change color to make more obvious which selection mode Blender is. Other option should put a boarder in the 3d view window with different color to each selection mode.

About hidden object and meshes: If we hide some object in object mode the "eye simbol" in Outliner changes but in edit mode, theres no obvious indication about how many hidden element exists, so there could be a number in 3d view related to hidden elements.
