I definitely agree having just switched from excel to Monday, It would be way more efficient being able to move across columns with the tab key and have it be ready with whatever you needed to do. Whether that is pulling up the labels for a label column, pulling up the calendar for a date column, or being able to immediately type in any column that requires typing (i.e a text column, connect board column, etc.)
It is very inconvenient to have to click into each individual column when trying to input a lot of information as quickly as possible.
