On my Mac, changes in the folder structure or Finder sidebar appear in DPL’s sidebar in less than a second. Tested with DPL 6.1 on macOS Monterey on iMac 2019.
If you add info about your gear and OS, you can make things easier for the rest of us. You could also add that info to the name field of your account profile.

I failed to include some important information about the directory refresh. My files are stored on a NAS and I was updating the directory remotely on a Windows system. So I copied a large number of raw files to a new location and PhotoLab did not detect this update.
I was also able to confirm that an update done through Finder was detected immediately.
I have a lot more experience with Windows systems and I was hoping that an option like Right-Click (Refresh) could be added to the Mac version of PhotoLab. Networks are an integral part of many computer environments and keeping the file view up to date is very useful.
