Hi, just had a brief course of Monday. I like it very much as an overall overview, I hope some kind of future functionality will allow you to create such insightful and easy to manage overview, ideally of course linked to more detail in the project/list.
One thing that I do miss and would like is a summary option for custom fields. It would be nice if I could sum a custom field on list or project level (when not sorted), just like e.g. time estimates.
It would bring more consistency if custom fields and e.g. default fields like time estimates were treated similarly and allow both the option to add/disable and show a summary.
Hope that makes sense :)
PS: I used monday some years ago, but they have implemented some rather nice automations as well, but I saw those planned already.
