I have just updated to latest version of tweetdeck, suddenly noticed the detailed notifications in tweetdeck. These detailed notifications are the new tweets in your public timeline which you can read directly in the detailed notifications itself. [ as shown in the image below ]

These detailed notifications are good, but after some time I found them just a more time waste and disturbing while working on something. So if you experience the same here is how you can turn of the detailed notifications and summary on or off in tweetdeck.

Go to settings of tweetdeck, click the notifications tab 

click on the text Detail On to toggle the detailed notifications on and off in tweetdeck

that’s it Done
