With more and more users going to larger and larger monitors we now have room to dock more items and help increase ease of use.
Others have posted to make specific windows dockable, I would ask that we have the ability to dock any window. Other than processes that are Dialog windows which called up and ran from ArcTool Box. i.e. we don't need to dock the XY to Line Dialog
Often I find myself with Find, Select by Attributes and Select By location up all the time becuase I am using them a lot. It would be great to dock them alongside other windows like Attributes, Templates, etc...
However, it is great that we can now take these windows out side of the ArcGIS window and put them in other monitors.
