Speeder can now detect the status effects at the top of the screen (along with everything else). To see them, use the -stats console command. Speeder will display the icons and text for each status effect. I was only able to test with Witch minions so far, so I am not sure if it works with percentages (or other kinds of text). Feel free to let me know on Discord. If it works well, I will add a script command to check these status effects and their text.
This addition requires Speeder version 31+.
