I recently installed Linux Mint on an oldish laptop, mainly for net surfing, for which it seems excellent. I've installed Gimp 2.10 and have occasionally used it for image editing, but having used Photoshop for many years, and being of an age where learning new tricks is more of a challenge, I nearly always end up tearing my hair out trying to find things in unfamiliar places, or grappling with unfamiliar nomenclature. One example, when using "Save As" it only seems to save in the native Gimp .XCF format. To save as a JPEG you have to use "Export As ..." and laboriously select .JPG from a list. Even though the original image is a JPEG. I could go on - can you use the crop tool to crop and resize to a particular pixel size at the same time as in Photoshop? OK the question - can anyone suggest a strategy for helping me to use this very powerful programme without frustration? Thanks in advance. (I've also installed Raw Therapee and Darktable, with similar bafflement. I find myself using poor old Faststone, which runs under Wine with some peculiarities, such as the Rotate Left & Right tools not working).
