I'd like to set up a block which updates its text every second, but also does something else when clicked. Is this possible? I don't see anything in the documentation, or in the issues (although I might've missed it there). Something like this:

[testblock]
command=./repeatingscript
interval=1
onclick_command=./onclickscript

where repeatingscript would run every second, and onclickscript would run when clicked.
