@delu has brought up the issue that, as of Bitwig 2.5 (on both Mac & Windows), info data for plugins is not read.
On the left is a regular non-rust-vst plugin. On the right is a rust-vst plugin. Note how the parameters do not display properly, and how the title is blank.
I will create a GitHub issue for this once I get out of work. In the meantime, feel free to postulate or discuss this issue and its impact here.
