Hi!
First of all, thank you for this great package! I am using it every day!
I am not an Emacs expert, so I hope my explanation makes sense.
Most of my day, I use a super agenda with scheduled tasks for this day that looks like this:

The problem is that I can't use the spacemacs leader keys when the cursor is over a line that represents one of super agenda's generated category headers.
It is very irritating, because normally you can use these commands from every buffer. It also works with the single lines of the agenda entries or blank lines, only the category headers cause errors.
, causes user-error: Command not allowed in this line
SPACE or TAB causes command-execute: Wrong type argument: commandp, spacemacs-cmds
I was not able to find a fix for this, but would be happy to help!
Best,
Christian
