It would be helpful if there was a checkbox in the QGIS QFieldSync extension that allows me to turn the project on and off after synchronization. In this way, I can also start a synchronization from other projects without closing them.

Application example: Instead of the Qfield-optimized project, I use a separate project for QGIS in the office, which accesses the data from the project folder of the Qfield project (what should be synchronized). Instead of having to open a new QGIS window each time to synchronize the mobile project, I could then simply start the synchronization from the QGIS project for the desktop PC.
