What you described is something we'd certainly love to support! However, I don't quite understand the need for 1). Channels can be grouped, so arranging the 1-bit signals in order and grouping them into one signal is already possible. As for 2), I'm not sure if the VCD im-/export module uses grouping yet but that's something we'll want for sure. Point 3) is non-trivial but on my roadmap. I'd like you to check out the great work already done by the folks over at http://www.ipdbg.org/ and also their github repo: https://github.com/LUMERIIX/libsigrok I haven't yet reviewed their changes but their code is already in working state, so that's definitely a good start.
