How many paid addons, paid styles have you bought for your site?

[sweetpotato]

It has been a year since I convert my site from Vbulletin to Xenforo. When my site built on Vbulletin Suit I bought many paid modifications and used all of them with one style. I didn't have to change modifications and style so I could only focus on building content for my site.
When move to Xenforo I have bought some paid addons, include:
TAC(Tenants Anti-Spam Collection) - Anti-Spam Complete Collection
XenCentral Multisite System
Social Connect (for Facebook and Twitter)
XenScripts WordPress to XenForo Bridge
[bd] Social Share
However, some addons become useless such as Social Connect and Xenscripts because no further development. When stop using Xenscripts I also had to drop integration with Wordpress. This make me wasting a lot of time and could not focus on building content for my site. Site traffic also decreased so much.
Now, I think I should stop upgrading my site software about one year to save time for building content. I like Xenforo default style but some people says it's necessary to have a paid style for site. So should I buy one?

How is that useless? Where did it state development has ceased on this add-on, I never saw @Chris D say that is was not ever going to be worked on again. I skipped back a few pages and didn't even see any suggestions from you as to what could be added to enhance the add-on itself. If you feel things could be added, please post them in the thread. Chris has always been a dev that does listen to customers, and adds what he thinks makes the add-on more complete. He doesn't just shoot ideas down to do it.

Anywho, that's my list that I can see. I scanned pretty quickly, so not sure if I missed any or not.

To many to list over the years.. Many i have no use for but purchased to test or the plugin was replaced by core functionality.. So in reality i'm only actively using about a dozen premium or custom plugins on various sites. OF course that isnt including free options.
