Hi @peppedeka
thanks for your contribution. could you move the clear button inside the "REDIS RESPONSES" h3 tag and position it on extreme right ? Also if we could use an icon instead of the "clear" label would be great!
Thanks so much!

HI @andrea82
fixed!

Ok... almost perfect. Is better to keep layout style for clear button as well, so if you could add the following style for icon and remove background and border of button style will be perfect.
.h7 { font-size: 1rem; color: #7a0c00; font-weight: bolder; }

thanks.

done!
