I just want to do something I've been doing for years before - sync the keybinds I have set in PHPStorm, especially those for the plugins I use across IDE's, and import them into other IDE's.
Since you decided to make cloud settings syncing mutually exclusive to having access to Import/Export options for the settings of course the first step is to disable syncing.
This is what happens when I do exactly that in PhpStorm 2019.1...
How do I export the settings now when they get reverted the moment I disable syncing!? I have absolutely no intention to manually make all the changes across IDEs.
I honestly have no willpower to deal with settings related issues in your IDEs anymore, especially after each update when randomly creeping-in issues completely cripple my productivity.
This issue (settings randomly reverting to IDE defaults) has been first reported almost two years ago and appeared in at least two dozen issue reports in the meantime but it's still not fixed.
Get your priorities straight and understand this - your settings syncing plugin is utter garbage. It's been nothing but royal pain in the grass since it's inception a couple of years ago. But in the meantime it was at least possible to manually export settings as backup and even import them into other IDEs with zero issues. Why you felt the need to reinvent the wheel is beyond me.
