^{Originally posted by jacobgexigo April 12, 2022} Just wondering if you could add the capability to attach the GUI to multiple repositories and just switch between them? The thought being if you had internal resources you wanted to monitor and also contract work servers to monitor and just wanted to keep them separate at the repository level (for many reasons).
