Not all platforms react in the same way to CLI commands.
While e.g. in Windows, among other things, the CLI parameter -reset-deltas
reacts as expected, the process reacts only to a limited extent in other environments. If this e.g. run on a Synology in this way as
/var/packages/syncthing.net/target/bin/syncthing -reset-deltas
Although the process starts, it does not work as required, even if the syncthing process is stopped. Such differences also lead to uncertainty when the processes show up differently.
The feature request would be that all CLI functions are integrated into the GUI so that their correct and efficiently usable functionality is given. This would also simplify the support.
