It's not even needed, I dont get what's the point of a post like this or why people bother replying. OP's primary example is an image viewer. There is literally only 4 of them that fit the criteria for what he was looking for in the list, feh even has it's own archwiki page and the 3 other have a link to either a website or a github page. He says he wants support and compatibility so he can cross off ximageload from the list, that narrows it down to 3. One of them's description mentions it being good for tiling managers and the github page gives a bit more info on it. Considering he wants compatibility, and feh literally has an archlinux page, shouldn't it be pretty much common sense as to what application he should use?
