More info about the app

Make Readme.md and description on XDA more informative: add screenshots with options and interface, copy info from XDA here too and add links to XDA and Xposed Module Repository. Tell in the info the advantages of this app over other ad blockers: MinMinGuard, AdAway. Is it conflicting with MinMinGuard, if so, which is better? Does the app need root? Does it remove space that was occupied by ads?

Review the current Readme.md, the XDA description, and the Xposed Module Repository entry. Inventory the existing app options and interface so the README can include accurate screenshots, copied information, and links. Verify the listed questions about root, ad-space removal, and compatibility with MinMinGuard; done means the requested documentation is complete and factual.
