As matter of fact, I don't mind how Joplin syncs, the real issue for me is that when Joplin syncs, it is hauling my keyboard input for like 0.1 to 0.5 seconds or so, and that is quiet disturbing and distractive when I am taking a note. In order to smoothly taking my notes, I had to go to setting and change the synchronization target to "(none)" so that I can type in a normal way, and then change the setting back to Dropbox after I finished typing...there is something really wrong in my user experience...
