Add more options for custom borders
I'm trying to add borders only on two sides, and not on the others : on the top and bottom only, to give the photo a cinematic look. But I can't find a way to do it with the current options. I tried to set a very unbalanced ratio for the borders : 1:500, hoping to have a very very thin border on the left and right sides. But it's not working (or maybe I don't understand how to use it...). Even a simple 1:3 is not giving me what I would expect : much thicker borders on the top and bottom compared to the left and right borders. So maybe there is a bug with the ratio.
And ideally, I would like an option for 0 border on left & right (or top and bottom).
