Both my macs on Mojave 10.14.3 have the same performance issues too slow while clicking the arrows and building the previews when first open a folder full of jpgs images.
iMac (27-inch, Late 2012), 3,4 i7 32gb, nVidia GForce GTX 680MX 2048
MacbookPro (15-inch, mid 2012) 2,3Ghz Intel Core i7, 16gb Nvidia GeForce GT650M 512MB/Intel HD GRaphics 4000 1536MB
Would like to know why the font is smaller as I can barely see what is written on my 15'' laptop also if there is a way to move the toolbar (that was moved from the top toolbar onto the right side panel) to the left side of the panel on top of Favorites or move it above the right panel folders on the right side panel? As it is it's cluttering the Folders as we need to move the mouse over these tools and sometimes settings change by mistake (this wasn't on PM5 as it was very clean the right side panel only with folder on top). If we have too many folders open it's a pain to deal with while having the tools under them, why you guys put these tools (Loupe, scale, filename, reverse, colors and stars) under the folders and not above or give us an option to choose where we would like them to be? We use the folders more than those tools.
Wouldn't have been better to sent a demo version to a couple of us before releasing this to the public?
This will create a very bad mood and feeling around PM as it is, even worst announced as a new super fast version, that for a lot of people will not be and you guys new that. Well for me I can say that so far I'm very disappointed with this new version 6 after all this time waiting for a major release and could not see anything justifying the $86 you are asking for the upgrade (it looks the same as PM5 except it's slower and more sluggish) in this case for me is a downgrade until it's fixed, very bad marketing move guys, hope this won't spoil your reputation and name.
