To preface: I am not the creator of this website. That goes to "Ora" one of the helpful people in my Unofficial Weak Auras Discord channel.
https://wago.io/
"WeakAurasGO" is an alternative website that is meant to completely replace Pastebin for sharing auras. It has some of the same functionality, but actually decodes the string given by the Weak Aura and allows you to see and make changes to the code/table from within the website.
It features a description section for you to detail your Aura as well as previous versions for if you're a custom aura coder and want to roll back, which will in turn produce new encoded strings to import into the game. (The process which can be found within the actual code of the addon)
Please give it a try and leave comments/suggestions for improvement. REMEMBER: Its still in 'alpha' stage, so there will probably be some missing or broken features, just let him know what you want / need / cant do. The link for the Discord channel is also on the website for more discussion.
