My variant of (txt)cliphist

[atagtm]

There are 2 main changes from the original one.
First, I place the selection into clipboard too, because i have difficulties using only primary.
Second, if i select a "link" from the history the notification shows a qr code. It is very helpful to "share links" to my phone :D

Because of the QR thingy it requires extra/qrencode to be installed + i use aur/fim to open the image if i click the bubble, but it's optional.

PS: I use extra/dunst as notification daemon
