Show message priority on messages

Still experimenting with Gotify.

With the curl commands i get two messages in the webGUI and the mobile app.
The webGUI shows a brown and red left-border (why does it not show the number somewhere? for example on the hoover event)
But the mobile app does not show anything related to the priority level. No color or anything.

curl -X POST http://gotify./message \
-H "X-Gotify-Key: " \
-F "title=title" \
-F "message=Priority 4" \
-F "priority=4"

curl -X POST http://gotify./message \
-H "X-Gotify-Key: " \
-F "title=title" \
-F "message=Priority 8" \
-F "priority=8"
