Allow line breaks between icons in the icon popup

[nilsboy]

It would be great if it was possible to add line breaks between icons in the icon popup to separate search engines by category. This would make it easier to see what engines are available for a specific topic. I.e. the first icon line for general purpose search engines, the second one for programming topics, another one for music etc. This also helps to distinguish searches on the same site for different topics - i.e. several searches in different subreddits at reddit - which all have the save favicon.

Thank you for considering this.

I have a few notes and "to-do"s written for letting users customize the popup panel. However, I wish Mozilla would get their stuff together regarding Firefox add-ons. SSS as it stands might cease to exist by the end of 2017 and there's little I can do, so it's demotivating for me to even work on it knowing that it might be for nothing (issue #24 for reference).

This is all to say that I'll likely only do the simpler kinds of updates until (if!) Firefox supports reading the browser's search engines on WebExtensions add-ons (SSS will have to be a WebExtensions plugin to even survive). I was not thinking to configure the popup as deeply as you describe, but your suggestion is good and will be considered for a possible larger update. :) Thank you.
