Having a few selected actions like, open_url, close_all ... is nice.
But I want do more than that on my notifications like:-

• if volume notification is their, use mouse wheel to increase or decrease my volume
• if brightness notification is their, use mouse wheel to increase or decrease my brightness
• if I get a notification, and on the basis of which mouse is clicked, I should be able to run my own script.

for example:-
I have setup a notificaiton system that sends me notification if price of something is low.
then being able to attach a script that gets triggred when I do different mouse click would be great.
If I press left click run script that buys that item,
if I press right click don't buy that,
If I scroll up, increase the bidding
if I scroll down, decrease the bidding
