This was the question of a few others. So, let me answer it once for ever
No special goal for here. add-ons that I share here has 2 reasons:
- I create add-ons for my site and then share them so that others also use
- Some people ask me to create some add-ons and when I do, I share them here so that others also use them
- you may ask why you create add-ons when your job is completely different thing? good question. I accept custom works to get $ in my account while I'm in countries that are under sanctions (cause I can't use my bank account to pay for my needs or add money to my paypal, so the only way is to ask friends to add money to my account <which is not good> or getting money by selling things or giving services and getting the money in my pp)
- second question that you may ask is: then why you share them freely most of the times?
again good question. well, I let everyone enjoy the works, and those who really enjoy and keep using them, may donate one day. when they get it freely and use it freely and then donate it, that money is 100% from his/her satisfaction and I enjoy spending it 
- third question: then why some of add-ons are paid?
well, those really should be paid. I mostly set those as paid that no one paid for it to be created and also took more time to be completed. (so, in +90% of the times that people pay and ask custom works, I share them freely)
But by coding, I have a personal goal which is not related to xenforo at all. Its related to my main job (my law firm) and so I will keep learning more and more how to code. (I'm in LEARNING LEVEL now and its better not to call me DEVELOPER for now. to be honest, REAL DEVELOPERS are just a few numbers in this community like
@Bob @Arty @Xon @Chris D @Mike + just a few others. its more correct to call me and lots of other people like me here: ADD-ON CREATOR or if you really want to make them high, then CODER

)
well, yeah. just need free time. I have a couple of other custom works that I may share here. Just need time.
Your welcome

hope you enjoy using them.
