Add "estimated time" as an option to quantify milestone progress via burndown charts and the sidebar
It is currently possible to use burndown charts to quantify milestone progress in "open issues" or "open issue weights". I think it would be of value to add an option to show "time remaining", which would be based on the estimated time for each issue (and updated as
/spend is used for individual issues). Likewise, adding "Total estimated time" to the sidebar just under "Total issue weights" would be helpful.
