Created attachment 257 [details] PV trace groups How to reproduce: 1. Remove ~/.config/sigrok/PulseView.conf to start with a clean slate. 2. Start "pulseview" (no options) 3. Open the file uart/voltcraft_vc940/voltcraft_vc940_multiple_modes.sr from sigrok-dumps. 4. Ungroup the default trace group, add two new ones, including a nested one (see screenshot). 5. Close PulseView. 6. Start "pulseview" (no options) again. Expected result: The trace groups are restored (but they're not).
