Filter option for Layout - Models - Groups/Model Pane

[Indigogyre]

Is your feature request related to a problem? Please describe.
When working on a particular group of models, sub-models, and groups for specific props requires a lot of scrolling up and down between the props and groups.

Describe the solution you'd like
It would be nice to click a Filter button, enter a keyword or phrase to limit the view of the models, groups to only the ones that match the keyword such as "Flakes" to show everything that has the word "flake" in it.

Describe alternatives you've considered
No other alternatives have been thought of at this time.
