Hi @Noob2this , I might not be the best person to answer this but I'll take a shot.
In the countdown timer macro, In the action labeled Custom Floating HTML Prompt, there is aline of text like
<body style="background: #ffd096" data-kmwindowid="Archive MD5 Tamper" data-kmwindow="SCREEN(Main,MidX) -940,SCREEN(Main,MidY)-800,120,55">
That is where you could change the display location.
#9c96ff is a purple color - you can change the color in that above line of code...
Not sure how to make it transparent, - I'd like to know that myself!
I hope this helps
