My question is whether there is or there will be a coding standards document that xenForo uses and xenForo modifications should abide to. I understand that it will be difficult to 'police' this when more and more modifications/plugins start rolling in, but it does set the tone and does help in the long run.
One small example that I can give you is the use of tabs vs. spaces on code written in plugins. Also what is the default tab? 4 spaces or 8?
Something like that would help IMHO.
