I personally found it very hard to keep track of all the great Plugins, Behaviors and Effects that are available for contruct 2 so far, so i made a little tool to quickly check them out:
It previews the Plugin/Behavior/Effect and allows to download and install it with one click.
For plugins that are hosted on own webspace or paid plugins the program allows to visit the homepage of the author / website to buy the plugin. A forum link is also provided.
Currently i've only added a few samples in each category for testing purposes because i was wondering if anyone else is even interested in something like this.
