i posted a tweet earlier today about an idea for making rich presence's easier! basicly there could be a tab for "custom rich presences" where it will greet you with a blank box without the logos and text. it will give you a logo place for you to either drag and drop, or choose a path to insert a picture. next to it there will be a text input box, with the label: "game/title" there you can add the title. ther will also be a "enter game" that willl let you input a path for the game, to automaticly trigger the custom rich presence to funcion. under it there will be a info box with label: "info" there you will be able to enter text, like if you are editing a video, you can enter: "editing (and then the project name)". next to this there will be a box called "advanced options" where you will be able to set if it should say "playing/watching/listning to" or possibly "enter custom prefix" that will allow the user to set a custom prefix (for example: if your editing a video, it can say editing) and if it should be overwritten whilst in the background (so if you have the application with the custom DRP on in the background, and open a new application, if it will say the new application instead of the one in the background) and if it should display automaticly!
thats all i can come up with at the moment, but i trust the devs to bring us their additions :) sorry if there was some spelling mistakes, im on the phone, and i often hit the wrong key.
