Drag-and-drop import of MOGRTs really helps speed up my MOGRT testing workflow, but one quirk of Premiere Pro that creates friction is that drag-and-drop import ONLY works when the Browse tab of the Essential Graphics panel is visible. If, as often happens, the Edit panel is visible when I am trying to drag in a batch of MOGRTs to test, I then have to switch back from Windows Explorer to Premiere, bring the browse panel forward, go find my Explorer window again, then drag the .mogrt files into the panel. This can happen dozens of times in a session when doing iterative testing of MOGRTs built in AE, since the last action in Premiere before revising a MOGRT is usually editing the properties in the EG panel.
If any tab of the Essential Graphics panel allowed the drag-and-drop import action, this workflow would be quite a bit less frustrating.
