Thank you! I tried to take a screenshot but as i press any button the icon disappears. It's problematic not for the icon itself, but the fact it makes it difficult to properly use the middle mouse button.
Yeah you would have to use an auto-screenshot program with a delay to screenshot that, whoops .
Anyway, thanks to the JS magician Armaldio I've got this for you:
1. Add the "browser" plugin to your project
2. Add an event "on start of layout" (you might have to use it on a globally included eventsheet)
3. Add the browser action "execute Javascript" and use the code from below
4. Set an ID for the form element(s) where you want to prevent middle clicking
5. Replace the ID inside the script with the ID you want to use (I've already set "test" as the ID in the script below, just replace the word after the "#" to whatever you like.)
6. Middle clicking is now no longer an option, you rule over the middle click function now!
"$(function(){$('#test').mousedown(function(e){if(e.button==1)return false});});"[/code:2ds8i2fa]
[i]By the way, I think that it should be possible to implement features like this into the plugins themselves.
If someone thinks about doing a "form +" plugin with additional features, feel free to add the stuff from above.[/i]
