RIDE soon to migrate to another web domain, announced in the new version of the application, while this web domain silently ceases to function! Please update your bookmarks/links once the new version of RIDE is out!
Yes, you can! See the application repository (click on Help → For developers → Repository menu command) and create your fork. Ask then for a pull into the main branch when you are happy with your modifications!
