Grouping Columns and Collapsing in Main Table

My team and I currently use all available tools to keep our columns organized, such as hidden columns, custom views, and filters. However, with a large number of columns in our main table, it still feels cluttered and difficult to navigate.

I’d like to request a feature that allows us to group columns (e.g., “Colours” group > Red, Blue, Green) and collapse or expand the entire group for easier workflow management.

While it is currently possible to collapse individual columns, this isn’t an ideal solution, especially when the column name isn’t visible while collapsed. This requires users to expand each one to identify its contents, which slows down productivity and undermines the benefit of collapsing in the first place.

Column grouping with named headers and collapsibility would be a major improvement in usability for teams managing complex boards.
