0xAli (ID: 000000ae451f9b55) Voted 5 ★ - Updated 01/04/2023 Awesome extension to Portfolio & coins track. I see an issue with showing coin price on the toolbar ext. icon, I think displaying price with double floating number (0.00) is the bad idea. Please fix that.

icon

Mariusz Stępień (ID: 000000f16fa621ca) Voted 3 ★ - Updated 12/21/2022 The number displayed on the extension badge has issues with rounding and it so long it needs to scroll to see the value since most of it consists just of "x.x99999999" making it basically unusable
