Show full object name in tooltip on mouse hover in outliner

If you use long names for objects it's pretty frequent to have them partially or fully obscured in outliner. Then to read these names you need to move your eyes to viewport overlay or have object data tab open which takes time and interrupts flow.

So I suggest to show full (not cut-off) name right there in outliner, inside tooltip if you hover you mouse for few moments.

Alternative suggestion is to also show mesh data name, this is also very helpful if you use objects with linked data.
