v2.1.0

• Completely changed how search results are displayed. They are now rendered as tree views which allows multi-selection, search, hiding desired rows, keyboard navigation, easy collapse/expand of multiple rows and more!
• Unused objects among the searched objects can now be found (experimental)
• It's now possible to search unused material properties, as well (e.g. normal map of a material that no longer uses normal mapping)
• Class/interface inheritance references can now be found (not always possible due to Unity's limitation in the used API)
• Most settings/colors can be tweaked from Project Settings
• Asset Usage Detector window can now be locked. When all open windows are locked, "Search for References" automatically opens a new window
• It's possible to configure whether clicked search results should immediately be selected in Hierarchy/Project or only on double click (or never at all)
• Optimizations and bugfixes
