As I've been converting my theme variant to 1.1 I've noticed some ugly things in the new 1.1 base theme.
1) Why does this font-family line exist? For linux you've left off all linux fonts you try elsewhere and actually end up with serif instead of at least sans-serif as the fallback like everywhere else. Why are these particular headers even trying to pull from a different font family at all?
.codeheader, .quoteheader, .expand_pages, .table_head > th, .topic_sorting_row > h3, .topic_name h4 a, .poster .name, .keyinfo h5 a, .keyinfo h5 a strong, .ui-dialog .ui-dialog-titlebar, #creator dt strong, .settings label, .popup_heading {
font-weight: 600;
font-family: "Segoe UI Semibold","Segoe UI","Helvetica Neue Medium","Helvetica Neue",serif;
-webkit-font-smoothing: antialiased;
-moz-osx-font-smoothing: grayscale;
2) The topic icons on the editor page (where you select the icon) are the old quickbuttons graphics but then out in the topic index where they are displayed they're different svg based icons. Odd to pick from one set then have the world see a different set.
3) <span class="topicicon" img_normal> has a line-height of 2em, but the :topicicon::before that puts the icon into the span has a fixed height of 16px. So if the fonts get scaled they look bad. They should be sized to 2em or at least something in em so that they will scale with the span.
