We do appreciate you bringing this back to the top and to front of our minds.
Since December 23rd when we first released we have addressed over 200 requests and improvements (that's 200 in 264 days! - bug fixes not included) and we currently have a list of 218 feature requests in our backlog. They're all important to the person who requested them, so we have to look at each request with a view to our overall goals, the difficulty of developing the feature and how it fits with the product plan.
In September Chris and I will be at IBC and will spend time reviewing and revising and we will certainly take into consideration Markers on the timeline.
Thank you and luma fusion developers team
