Files & Content page - Folders and Page Tabs

The current contents page lacks the ability to properly organize and group files together. Being able to have sub folders and ideally different tabs to organize all the files would greatly help keep stuff more clear and organized (E.G, Folder for texture files, Folder for Unity files, Folder for Misc files). Having page tabs which you can store these in would also allow for better documentation associated with the files, the current text field results in a info dump and causing people to search through it to find the information they are after.
