On the project homepage, you can sort all of your projects based on their "Creation time" or "Update time". If you choose "Creation time", the project that has been created most recently will be listed first. If "Update time" is selected, the project that has been updated most recently will be listed first.
Sort Projects with Drag-and-Drop
You can reorganise your projects in a custom order. Ensure your sorting options in the upper left corner are "Default", then you can then drag and drop to organise your projects however you like.
