Thanks to feature (https://leankittools.uservoice.com/forums/17754-new-feature-ideas/suggestions/915331-analytics-should-include-burndown-chart?ref=title), it's possible to see burn down/up projections.

However, the default chart generation is often not usable because chart generation settings - such as, use card sizes, start date, end date, lanes include/exclude, lanes collapse/uncollapse etc. have to be set every time a chart is generated. These settings should be rather board settings defaulted to all users, rather than having to set every time by every user (and at the same time expecting them all to know what to set, in first place).

In similar manner, the charts, with the right generation settings, are not currently reachable via URL, making them very hard to share as well (e.g. include in reports).
