Not so good image browsing

I edit pictures on the network drive and this app disappoints me, I constantly find myself using other apps to get things done that this app should do without a problem. When browsing files on the SMB shares, the app freezes up my Mac pro to the point its not possible to switch to other apps and I have very fast machine. Also services option, in Finder, does not work as expected. While developers responded quickly, the problem is not solved, even in an updated version. Right now just keeping it as backup app to open unsupported files.
