Possibility to invert the X and Y axis so the track goes vertical instead of horizontal while playing. This would look like a Tracker (similar to Renoise, for example), which would give to some creators a better feel to make straight-forward bangers. 
What problem(s) would this feature resolve?
Users coming from a tracker background (Renoise and others) are used to having the time bar on the vertical axis. Allowing this as an option would make it easier for these users to feel at home and being more creative.
How does this feature fit in Bitwig as a product?
Higher user acceptance and conversion.
Is there already an alternative way to achieve this on Bitwig?
No.
Could it be implemented using Bitwig components or APIs, without Bitwig team’s support?
No.
Could it be provided by an STV or something else reasonably integrated with Bitwig?
No.
Are there other products that offer this feature?
Renoise and other traditional trackers.
