When you hover over an image, you can choose Menu > Preview Image. Then you have a list of thumbnails down the side and a large image to the left.
Thanks! That's exactly what I was looking for.
ETA: Okay, not exactly what I was looking for, but I guess it'll do. Playing around with it, I just realized this switches views and hides the filter panes and I have to close the preview window to get back to the filtering view.
Great to see that you're using MC to manage your pictures. In recent years, it's become one the most overlooked areas of MC, in my humble opinion, of course
I use ACDSee as my image file manager, and I've tried numerous times over the last decade to switch over to MC, but ACDSee just more streamlined in terms of the viewing aspect of images. Little QoL things like being able to marquee zoom (i.e., drag a bounding box), image viewer vs. image manager, etc.
Problem with it is that there is an internal hard-coded limit to the DB size, and I'm constantly having to prune/delete the thumbnails lest I get a "database corruption" problem (false error).
Anyway, TMI, I know, but I'm giving MC another go. My new beef is that MC now won't display animated gifs at all. It never animated them, I know, but with v23, it won't even display the first frame. I'm hoping that's just a bug that will be sorted out soon.
