I can only use the 'grid' functionality from the Timeline view, not from the default Tree/List view.
Timeline:

I am unsure if this is by design, or a bug. Please let me know.
Thanks.
Hi all, We have released Table View! 🎉
Quire's Table view transforms your task list into a structured database format, offering a spreadsheet-like layout that enhances organization and visibility of information at a single glance. You can also include your unique custom fields in the columns on the Table View.

Another vote for "grid view". This new feature combined with "custom fields" would allow a all new level of organization!

Hi,
It's our purpose to have Grid view on Timeline only.
However, we're considering adding Grid view to the Tree view as well.
Stay tuned!
