Welcome to XF2 Addons. You can buy my Premium membership for $35 per year, and this gives you access to download any or ALL of the 250+ add-ons that I have developed for Xenforo 2.x. In addition, Premium members will get technical support. Once the Premium membership has expired you can continue to use the installed addons on your forum as long as you like.
I think $150 for 5 years would be a good happy medium. Most forums don't last 5 years, nor update add-ons regularly, so would probably be a net gain for Andy and help fund his up front development costs for new add ons.
I'm using 74 of Andy's Add-ons. Every one fills a need not provided by XF out of the box. It's an incredible value. I've told him many times he should charge more, but I do volunteer my time testing and suggesting fixes which he is very good about making if he feels they are warranted. Andy...
Remove Attach Limits Plus 1.3 was not compatible but was replaced by Attach Limits 1.5 which is compatible*
*there appears to be an issue with Remove Attach Limits 1.5 causing resizing images in XF 2.1 to not work
Yeah, I realized that after posting this. I was looking in the Resource Category settings. Would be nice to have it per category (like default sort is per forum node), but that's probably more of a core feature change. I'll suggest it on the official forum.
Same (or similar) hack should apply to XF2, but you are altering the table and minimum in core XF code/tables, so any update to XF will break your hack (or worse, your site) and you'll have to re-apply your hack.
