We're looking at upgrading from 9.x to 10.x (possibly 11.x when it releases) and I've taken a look around the new portal.
My biggest gripe is the custom links. It took me a bit to figure out, but all the icon images seem to be taken from Font Awesome (or more specifically, a small included subset of the icons found here - http://fortawesome.github.io/Font-Awesome/icons/
I'm sad to see that our custom links suffer a fate where they are text based only and no longer include an image by default without some major CSS customization or hacking. This somewhat alienates the customer experience that our customers have come to with our wickedly styled icons in version 9.x.
I feel that SmarterTools should create an additional form for custom links that allows us to input either the Hex code for a Font Awesome icon or the name (fa-<iconname>) to assign to the custom links. SmarterTrack should then easily stylize the link for us using the same CSS that the main links use (home, KB, News, Ticket, Community).
I also feel that ST should give us to the ability to easily change the icon type and name of the stock links as well (so we can differentiate between another customer's system and be consistent with the user experience on each individual Support page). My Knowledge Base icon can be fa-book whereas another KB icon can be fa-database (like the good ol' days).
I have seen that you can enter this into the Announcements part but it isn't consistent throughout all the pages.
