As there is no other way to make such a simple thing like coloring different parts of string with different colours, I resoreted to use the Formatted Text extension. However, when I enter the string for the first time (after Select all), the app will lag. It got me thinking whether these things are using HWA or they are using some system controls?
As the extension is quite old, I would like to know whether it does not cause a bottleneck in performance..
