A lot of Construct 2 Essential Plugins can't be ported to the C3runtime. Because of the lacking SDK features. A lot of Construct 3 plugins still doesn't support the C3Runtime. Either not yet, or can't.
That´s why I decided to only support the c3runtime if I make a new plugin. It saves me the headache of supporting two runtimes that work differnetly (I bet Ashley can relate) not to mention one of them is going to be deprecated in the forseeable future.
About the "lacking SDK features" and plugins that "can´t be ported"... what exactly is lacking and what plugins can´t be ported? I´ve never dabbled around in the SDK until recently so I dunno, I´ve heard that argument a couple of times but never with any specifics. Also... did Ashley say that he won´t implement these lacking features because reasons?
