Had a very hard time today describing a newbie how to do the most basic things in-game, it felt like ages, and after some time I start useing a program called Lightshot that you can use to select a portion of the screen, draw some arrows, then save and upload to Imgur or somewhere, sent the link to the newbie, and he see where to click, what to do, etc. Like this:
I think it would be a really great feature if we can do this in-game and send small pictures of screenshot selection with arrorws . Preventing retards it can be restricted to private chat and also a size limit. Saving server capacity it could use a smaller server and pictures would delete after 5 minutes.
you can replace default function of “printscreen” button to be the shortcut for it in app options although it doesnt work when some/certain programs are an active window
you can upload on imgur (and on these forums btw) directly from clipboard - no need to save the image and then navigate to it to upload. So its not THAT labor intensive.
