Browser Dock (like OBS)?

Hi - any chance we could have a custom browser dock within the Presenter UI, like OBS does?

This means that we can insert an additional (customised) control panel within the same space as the Presenter UI, e.g. to select an OBS scene, or select a sound snippet/preset, or basically anything else.

We can have a separate browser side-by-side to Presenter, but it would be nice if this was within Presenter.
