I wish I could see the pp with +HR in taiko

very good, works almost all of the time; can be slow to update for pp rebalances though

After about 20 seconds, a black square will show up in the middle of the extension window, and mousing over it makes other objects black. Closing and reopening the extension window is required to bring things back to normal.

Looks broken with HR for some maps. Not all them get star increases when you turn HR on, some stay at the same star rating. For example, in this screenshot, https://i.imgur.com/i8N7mo7.png you can see that HR is still 2.3 stars, but ezpp! says it's 2.54 with the same mods (HR) https://i.imgur.com/yqsrR30.png

would be cool if the addon icon in the address bar changed to a number to show the pp you can get from the difficulty at a glance, without needing to click it.

maybe have some options in the addons page to set if you want it to show for 95%, 100%, etc

Works perfectly
