The LibreOffice application icons are undoubtedly awesome. But over the years they have become a bit dated and do not fit well into the zeitgeisty icon design. Plus, the set has no good main icon, which is in particular an issue on macOS where this icon is shown on the launcher bar.
Many proposals have been submitted and finally the TDF members elected one concept in a first poll. Now we like to involve the larger community into the design work. The question is whether icons should be flat or have some gradient. Please use the following link to vote.
