Hello,
Thank you for your suggestion, much appreciated!
We’ll add your request to our "Suggestions List"
If you need it now, we can suggest you do it with CSS.
Example:
At the code editor add CSS code
.open-menu i:before {
content: '\f150' !important;
}
replace
\f150 to code of your icon
This code you can take from developer tools
