iOS WriteRoom editor feature replacement? One of my favorite features about WriteRoom is that as soon as I open it, I see a listing of a Dropbox directory I have previously configured. No extra steps. This lets me very quickly get to my notes and records without navigating around, since I always want to go to the same directory.

Since WriteRoom will soon become incompatible with iOS 11 since it is a 32-bit app and is not being actively developed, does anyone know which of the many text editors available has this feature?

Per @patrix suggestion, here are prioritized features for a Dropbox text editor:


Open directly to a particular Dropbox folder at launch, after a one-time configuration step. No additional navigation. Speed is #1!
Sync that Dropbox folder's contents to the device, so that it can be accessed offline, and the changes reconciled after coming back online
Text search through the entire folders files, and also within the file once it is open.
Sort the folder list by name or date, descending.
My suggestion is Ulysses. A pleasant, focused writing experience combined with effective document management, fast syncing and flexible export make Ulysses the first choice for writers of all kinds.

Here is some info about synchronisation with Dropbox. A quote from that post really describes the function you are searching for.


  Once your Dropbox account is linked, you can navigate through its hierarchy and choose folders to add to Ulysses’ library.


I do not have financial ties with Ulysses!
