No you don't, if both devices are using the same iTunes account. To activate 'Remove Ads' on your other device, just tap the "Restore 'Remove Ads' Purchase" button. You won't be charged twice.
When you delete and reinstall PlainText, your preferences are unfortunately wiped as well Tap the "Restore 'Remove Ads' Purchase" button in Settings.
Corner case: If PlainText continues to crash after you re-link from Dropbox, check your folder names. For a very small set of people, having periods in folder names seems to create a problem. It shouldn't, and we can't reproduce it yet. It might work for you, though, so please rename these folders on the Dropbox website or on your Mac/Windows computer.
Set your text editor to open and save in UTF-8 encoding. In TextEdit for Mac, go to TextEdit menu --> Preferences --> Open and Save.
You'll need to use a text editor, such as Wordpad or Notepad++, that understands UNIX-style linebreaks, not just Windows linebreaks.
For now, PlainText will stick to just plain text formats and Georgia, 18pt. Font choices, sizes, and color are part of WriteRoom's set of features.
If you're syncing with Dropbox, you can use their website to un-delete files and folders, or revert to previous versions (free accounts are limited to 30 days of file history, see this Dropbox page for more information). It's also possible that you can recover deleted documents by using iTunes device backups, but rolling back to a previously saved backup will have wider implications for your other data since the last backup.
In previous versions of PlainText, an alert customer discovered a potential data loss scenario that affected non-txt files (such as PDFs, video, or images) that occurred when renaming folders with these files in them. The problem doesn't have an easy fix so for now we have disable folder renaming until we can be sure this won't happen.
Sorry, it's not possible in the app. We haven't found a 100% reliable method yet. You can do file/folder rearrangement from the desktop or from the Dropbox website.
In Settings --> Dropbox: Before you link to Dropbox, tap the text field to the right of 'Linked Folder' then enter the folder path you want. Simply using '/' means you can access your entire Dropbox folder and all subfolders.
You need to unlink from Dropbox and relink before new whitelisted files will start syncing. In PlainText 1.5+, the whitelist is hidden unless you unlink from Dropbox.
In Settings > View > turn off 'Detect Links.'
If all your documents remained after unlinking and you later re-linked to Dropbox, this would also upload all the device's files and result in tons of file duplication and conflicted copies. That is also why your synced files are removed, but your unsynced files remain because they haven't had the chance to sync up with the Dropbox servers yet. Your synced files are still safe on Dropbox's servers.
Put your device into Airplane mode, launch PlainText (it should behave now), and unlink from Dropbox. Then, turn off Airplane mode and relink to Dropbox.

No, probably not. Dropbox currently has the largest customer base and the least headache-inducing API. iCloud support is under consideration but it's not in the immediate future.
Sorry, it looks like there's a bug in the AdMob binary which we can't access or fix. Until we receive a new, fixed binary, please use the quick-scroller (tap and hold, then drag) for large scrolling movements.
