it would be really neat if we could have a bug report button for plugins in the admin interface. its very often that you find a potential bug or incompatibility issue, but instead of reporting it to the community, you simply deactivate or even uninstall the plug.
i would like to see a small ajax button with a popup that allows you to post in a bug report discussion in an existing or new thread.
this way, i think we could address important bugs much quicker.
this function of course needs to be built-in on a central/core level in WP.
