Rather than having to choose between a date column or a timeline column, I’d rather have them combined into one column with maybe a checkbox option for selecting a date range if I need to. So, it would default to selecting only one date, but if I wanted to select a date range, I would check a “timeline” or “date range” check box (similar to the “add time” checkbox) and then I would be able to select a range instead. I really don’t like having to always predict whether I’m going to need a date range or not when selecting my columns, and I don’t like that I can’t put times of the day on my timelines. It feels like it would be most intuitive to have one column that handles all kinds of dates.
Hey @dlaina
We’re revamping the timeline column and we want your help!
My name is Amber and I am part of the team responsible for all the columns you see on your monday Boards 
We’re looking for highly engaged users to shape the future of our timeline column! As a design partner in this journey, you’ll collaborate closely with our product and design teams over the next few weeks and then get early access to the functionality that you helped design!
We’re looking for dedicated users who are excited to provide feedback and work with us to bring this vision to life. If this sounds like you, please fill out this form
Hi Amber! The form does not seem to exist anymore and we’re still looking forward to this feature build.
