Highlighted item when whispered

1.i barely see the highlight in the video
2.what if i have multiple whisper?
3.Is it possible for it only highlight when i click ACCEPT(something like that) or when i invite the person.If so, it would be nice if you can highlight with different color or something like that for different invite
For example, the first invited will highlight the item with White border
the second invited will highlight the item with Green border

AND, it will be even nicer if you can highlight the stashtab instead of i have look to the whisper to see the stash tab name

sorry bad english
thanks for reading

I added some suggestions for how to expand this to multiple recent requests and even go beyond that have an option to limit by people in your party, to weed out dead requests, here: https://www.pathofexile.com/forum/view-thread/3294074/page/1#p24698974

the stash tab name is in the whisper message.

when you get multiple whispers it will only highlight the most recent...which could make it much less efficient for big traders.

but yes, visibility of the highlight-frame is a issue.
