Ok, so this is fairly minor, but here goes: on macOS Ventura, even though the TotalFinder window itself did not play well with the transparency effects in macOS, the system menubar was still transparent when TF was the active app. However, this is no longer the case in Sonoma. If TF is the active app, the system menubar is opaque even if “Reduce Transparency” (System Settings > Accessibility > Display) is set to OFF. Again, this is not a huge problem, but it is visually jarring when the menubar is transparent (translucent, actually) for every other app, but becomes opaque when TF is the active app. Hope that all makes sense.
Can anything be done about this?
