Should be able to remove this.

[hsampson, 2016/02/08 04:40:23]

It looks like it but if I try removing any of the flex stuff it changes the
layout too much.

[calamity, 2016/02/05 02:30:10]

This is an interesting font size...

[hsampson, 2016/02/08 04:40:23]

Yea just copied it from md_downloads as there are no specs for this. Have
changed it to the same size as the card titles.

[tsergeant, 2016/02/04 02:28:49]

Can this be a computed function instead of a property?

[hsampson, 2016/02/08 04:40:23]

Done.

[tsergeant, 2016/02/08 22:59:01]

Meep, what I meant here was to create a function like

{{noResultsMessage_(searchTerm)}}

That way, the message would be updated automatically rather than having to call
noResults_ manually.

[hsampson, 2016/02/09 02:17:51]

Done.

[tsergeant, 2016/02/09 04:28:53]

This still isn't quite what I intended, but it does have its benefits. I'll
explain in person.

         <history-card history-date="{{historyDay.date}}"
+            search-term="[[searchTerm]]"
             history-items="{{historyDay.historyItems}}">
