Hi. I am looking for an app to read .txt files. I have tried apps like UBI Disk, Documents2, and even the dropbox app. They all read the .txt files, but they read the file from top to bottom without stopping and if you mis a part and want to here it again you can not unless you listen to the whole file again. I want to be able to navigate by sentence and if possible, also be able to edit the files. Dropbox support would also be nice but is not a requirement. I am willing to pay for this app. Any ideas? Thank you.
