Yup. Asset management is pain in the a**, but they're running a business here, community wishes and actions are not a priority and we don't know what information drives their decision to spend time on twitter plugin and such, but not on making asset management easier.
I really hope they let the community to create twitter-like plugins, and spend their time making C2 IDE a better place, starting with asset management and asset store. I cannot tell how many nights i spent tinkering on this problems, and just decided not to spend any time working on it seeing how Scirra reacts when community tries to make improvements on C2.
However, it such a great tool on many other fields. Let's give them time, for now they are doing an ok job. We cannot make IDE a better place, but we can create good plugins, and community proved that long time ago.
And yes, updating sounds is a joke that bites your a** late in the development.
Edit: Superb response time on a request (r175). IDE is a better place now regarding asset management.
