Very possible I'm just a dummy here, but I've searched the manual and haven't found anything there about this yet.
Here's my situation:
New job. Dev environment is a jail on a FreeBSD server. I've tried setting PhpStorm up with both SFTP and mount and I still have the same problem. Problem is that when the remote files change (git pull, git checkout to revert a file, whatever...) they don't update automatically on local. I understand that you can right click and select "Sync from deployment server", but TBH, I'm not too stoked on that.
Best approach I have so far is to do File > Open Directory on the mount. Remote file changes show up when doing it that way, but then PhpStorm's syntax highlighting takes a while to catch up. Likely because it's always trying to index in this situation. Not to mention the file path case sensitivity issue that PhpStorm always brings up when I use this route.
