App for text to dropbox

Hi folks,
I'm Jared, I was the one that mentioned that plain text 2 was having issues and tried to reach out via the site within the app. I was told that this app is no longer available. I'm seeking an app that is similar to what plain text 2 offered. Basically, I'd like an app that would open text files, and of course, allow me to write or dictate, and it saves in dropbox for when I'm at home and can edit it further, or take action on said item. More importantly, one of the things I had trouble with, was opening a 34k text file which is a log for paratransit trips, and it would not open the file. I don't need fancy formatting tools, and I don't mind if I have to tell the application to upload to dropbox. I would prefer it to do it by itself, but it is not a requirement. I've moved or deleted what plain twext 2 was managing for me in to folders and removed the app off my phone. Any ideas would help. I've seen names of apps in another forum topic, but I am several months new on the iphone and do not know if any of those are out there. Thanks.
