This is a big one. We're currently in the process of updating the entire user interface of the administration. We're rebuilding from the ground up using React and updated styles. These changes will allow us to more easily build new features, develop better interactive features, and have a more modern system. If we waited until the entire administration was complete it would be a long time to reap some of those benefits. So we are rolling out changes in batches. One of the first things we started workign on was a complete overhaul on the file browser. We will also be updating different sections of the administration and adding new ones as we progress. For the most part things will look similar to they are now, but there are some style changes that are coming.
