Add "Edit mode" to collection and by 2 click of LMB

Add "Edit mode" to collection (that was added multiply time) is required to more easy edit main object without searching main instance that creating this on outliner. Curently "Edit mode" is turned off, and withig betwen Layer and Modeling not giving option to edit. We should have option to working without outliner if is possible to minimize this type step and procedures. Swith to edit mode by 2 click of LMB can be fine in my opinion.
