You can activate single-window mode in Gimp under Windows -> Single-Window Mode. I would generally recommend Kubuntu over Ubuntu -- it seems like Gnome aims for minimalism somehow, and has thrown out a lot of functionality that used to exist, and generally tends to emulate OSX for a lot of things. (E.g., OSX doesn't do alt-tab for multiple windows of the same app either IIRC.) BTW, Kubuntu's default image viewer would likely be Gwenview -- You can get it to show a lot of information by clicking "More..." in the Meta Information panel and selecting stuff in the resulting dialog window. Here's a screenshot I found on the nets: https://www.fossadventures.com/wp-content/uploads/2018/05/Gwenview-05.jpeg https://www.fossadventures.com/wp-content/uploads/2018/05/Gw...
