[Plugin: Reaction Buttons] some new features

Hi, thanks for the great plugin! Please consider some more features:

• The possibility to use HTML in the Tagline – for easier formatting.
• The possibility to click more than once – presently multiple clicking appears to be blocked in any case (e.g. for logged-in users). It can, however, be necessary to click several times if you use the button to trigger a script, see also next point:
• In the options please add an additional textarea where I can insert some Javascript that would be executed on click events (and, if you like, also one for mouse-over etc.). This would make your button much more universal, you could use it for opening new pages, opening pop-ups for external services etc.. But it’s also helpful for the voting functionality, e.g. some feed-back.
  Ideally there would be a pre-defined placeholder for post id and author id to be used in the script.
  But it would be important to keep the counting and statistics functionality.

Thank you!
