Tentative Plan:

• add a search box or a search bar in the fragment where there are all the lines (this could be done nicely with a Floating action button)
• update the lines in the adapter, or find a similar mechanism, to show only the ones corresponding to the search

the lines have a code, like "gtt:4U" -> line 4, so it should be fairly straightforward. The barrato lines could be a problem, but we can ignore it for the moment

Probably the best thing is to include a search functionality in the action bar (the thing on top), even if it's not what I like. I'm trying to make it work with this design (see picture), but there are issues... (the search widget expands ehehehe)

Seems lovely to me, big Fabione asd
