Description Weng Xuetian 2015-04-22 06:12:03 UTC

It's common when using ktp and you missed more than 3 messages.

Since the notification is persistent, the popup will only show first three line of them.
It would be better if it shows last three line of the message.

Reproducible: Always

Steps to Reproduce:
Run
notify-send "a" "b"
notify-send "a" "c"
notify-send "a" "d"
notify-send "a" "e"

Actual Results:  
Only b, c, d are shown.

Expected Results:  
c, d, e are shown.

Comment 1 Martin Klapetek 2015-04-22 08:37:43 UTC

I'd like to make it even smarter and make it say

"2 previous notifications
d
e"

...but string freeze, so 5.4.

Comment 2 Martin Klapetek 2015-04-22 08:41:37 UTC

For 5.3 it could still show just the last messages with "..." at the beginning, but I'm on the edge here. I'm not sure if it's better to show the first messages as much as they fit or the last messages (the latter is certainly harder to do).

Thomas - what do you think? If you receive 4 messages, in the notification popup show

"First message
Second message
Third message..."

or

"...
Third message
Fourth message"

?

Comment 3 Weng Xuetian 2015-04-22 16:25:09 UTC

Actually I was wonder if it can be in reverse order.
Third message
Second message
First meesage

Because every message can actually longer than three line. Show last 3 message may not solve the problem. And cut the whole string from end may cut a message from end. For example
-------------------------------
...
ThirdThirdThird
ThirdThirdThird
Fourth   (<-------- this line is not shown)
-------------------------------

Or, make popup always show the latest message, and the message list show the whole history.

Comment 4 Thomas Pfeiffer 2015-04-23 22:35:31 UTC

Thank you for informing me about this, Martin!

Okay, here's my take: The last message/notification is most likely to be the most relevant one for the user (regardless of the application), so I agree that it should not be truncated.

From a user's perspective, the best solution would probably be to only show as many messages as fit in the popup in full.

If it is not possible to determine how many of the last notifications fit into the popup, following the above reasoning (and agreeing with Martin that a truncation in the beginning is quite uncommon), I'd recommend showing only the latest notification (as Weng Xuetian suggested).

Comment 5 Kai Uwe Broulik 2015-04-25 20:20:19 UTC

+1 on reverse order, prepend new ones and older probably by now less relevant notifications just fall off at the bottom when the maximum line count is reached.
