Some improvements to Amaze file manager

Components
Amaze file manager is an open source material design file explorer application for Android. It is top in categories of file manager. Here I am some improvements for it.
Proposal
I am proposing two features for it:
1)Categories:Amaze file manager is a good file manager and is used for browsing files present in our phone and memory card. It is very simple and easy to use. It has lots of amazing features but I think it should have an feature of categories in it. It is very important feature and makes a file manager good looking. This feature has lots of benefits that I will discuss below. This feature is present in MI file manager. Screenshot is taken from MI file manager which has this feature enabled in it :

2)Cleaner:It is present in MI file manager and serves to be good feature. Below is screenshot from MI file manager:

Benefits
1)Cleaner: As the word comes on benefits it has too many benefits. First I will ask you one question that why you keep a cleaner in phone likewise it will protect file manager from different types of viruses .Keeps our phone memory clean from cache or junk files that we don't need in our file manager. So it frees some space for more content.It shows apps that are not installed and if we need them or want to delete.Often sometimes our phone gets bulkydue to caches or thumbnails so we can find them easily in file manager. If this feature is present it will scan your data present in file manager and report you all junk files bulky files virus files and much more.Thus it is very important feature and it should be enabled in Amaze file manager.
2)Categories: This feature leads to easy and simple file browsing. For example if you have to find any video file you will have to browse through all file manager but if you are with this feature you simply have to click on option of videos and you will get list of all videos you are having in your device. Hence this feature has following features:
*It will make home screen good looking.
*It will provide list of all files categorically.
*It leads to fast and simple file browsing.
*No need to waste extra time in the file manager.
*Make Amaze file manager's screen efficient looking.
Thanks.
