I'm not sure I understood what do you mean under "choose smilies". Smilies are set up manually editing the file, as much as you could open templates/main_posts.html
and paste any codes you want, at any place you want. Each site mentioned has such codes provided on their pages. For example: code for Twitter buttons
- code for Facebook buttons
All add-ons you mentioned, can't live on themselves - you shall edit a template to paste their output, anyway.
Then what for we would need kind of special output, if you could edit template right away and paste the code for bookmarks directly? What is difficult or not clear for you, what do you need this add-on for?
BTW I agree to tom322, nobody know what those codes are about, and we at miniBB do not really support something which comes from 3rd party sites. It has been passed just 10 years since the fashion was around putting counters or webrings on sites, now everybody puts Facebook or Twitter, like it would help them a lot to grow, in another 10 years there may be other websites which you could advertise for free, getting nothing instead. I'm afraid it's not our politics, and if we talk about kind of visual tools for admin, there would be much more important work regarding add-ons for modifying miniBB options, else spending time for such efforts which are not really worth it.
Actually, if there would be 100 requests like this, I would think about writing an add-on, but since there is currently only one anonymous person requesting this, I think we will skip at this point, sorry -but thanks for suggestion anyway, and if you need it for your personal forum, you are welcome to refer to our customers service
