Hola Ignacio,

• ad 2) Not really, it's how FontAwesome works, in general, whole FA package (few files) is loaded. It's like font. Theoretically, you could overwrite those 3 icons using svg files that are actually used in the menu (>, ^, search) and disable Font Awesome. It would certainly be a ~200Kb reduction..... but that's your custom task. Hopefully, one day, these 3 icons realistically used we will try to replace in Helix update, so that they work even without FontAwesome.
• ad 1) Indeed template.css may use some files from orginal design. But please do not edit template.css file. But you can replace that file: menu-bg.jpg (19.7kb ) with a small one (1kb, 1x1px size) - if you don't use it. It will allows you to save ~19kb. This same if we talk about goal-fetti.png (2kb) file. It may not be much, but in total it's always something.

File path: templates\livesports\images\menu-bg.jpg

BTW

I noticed that you have error message from extra plugin, screenshot:

Is there a way to load only some icons from font awesome instead of the whole icon set?

Hi. You can create your own icon font using Font Awesome svg icons you need, icomoon.io and CSS. Then turn OFF Font Awesome in Helix and SPPB

Hi Paul. SVG serve only as raw materials to create an icon font. At the output you get a full font (WOFF2, WOFF + CSS stylesheet) containing 3 glyphs (for example), to which you can apply any CSS font properties.
