Right-clicking on an item in the Objects docker opens a popup menu. I suggest to extend it with the following options in order to avoid having to create search queries in Find:
Select all objects of the same type (e.g. rectangles, circles, curves...)
Select all objects with the same name
Select all objects with the same fill color
Select all objects with the same fill type (solid, gradient, mesh, etc.)
Select all objects with the same outline color
Select all objects with the same transparency
This would substitute a lot of the cumbersome insanity of Find and Replace for the most frequent cases with an easy to use, literally 2-click solution to find matching elements.
