Hi,
I've made a little client updated, which is displaying for 2 seconds how much experience you've gained. You need to restart your client for this update to appear!
To clarify things, I've taken a screenshot:

Do you like this? Is it more annoying than helpful? It's currently enabled by default. If it's annoying to see how much experience you are gaining, I'll add an option to toggle it off.
All the best,
Thomy
