[Feature] Icons Shortcut
For the sake of workflow we could imagine specific shortcut added to GameObject/Component headers as icons. Some other packages do it this way.
See favorite and Copy/Paste Icons added by an other plugin, you can right/middle/left click the icon and it has several behaviours (copy/paste)
One of my main motivations with Inspect+ was easily opening an object's Inspector in a new window (that was before Unity added the "Properties..." option to right clicked GameObjects' context menu). I don't think Inspect+ is useful as a complete Inspector replacement since Inspect+'s inspected object is fixed and doesn't change with Hierarchy/Project window selection. For that reason, I don't expect users to spend too much time inside Inspect+ windows (at least I don't) and I suspect that making UX improvements like this in Inspect+ window won't be worth the effort.
If you meant modifying Unity's built-in Inspector and adding extra buttons to components there, that's another story. Though it could be useful, right now I plan to keep the native Inspector functionality as is.
