Export/import to/from plaintext with basic Markdown formatting would be really nice. With "basic" I mean: no text styles, no checkboxes, just the sibling/child structure (and maybe support for notes).

This way we could do major editing with any text editor on the Mac/PC.

As it is now reducing font size ("small font") doesn't reduce line height. This is not terribly useful.

With "small font" also line height should be reduced (and accordingly the size of the triangle and checkbox).

I would prefer the following format: I.1.A.i.a. etc vs the current legal format.

I use master lists (eg for food shopping). I check the items I need then uncheck them when bought. A filter to show only checked items will reduce as I buy items but my master food list is retained.

Would really make it more useful if you could add the alarm function to an item not a list.

Search / Finde in Outliner Online
I also use Outliner Online a lot on my desktop, what I realy mis is a search/find function in the Online version, would be great.
Ctrl-F browser function doesn't work unless all's expanded, but then one has no overview on the outline

hello.
i think that it is more suitable that "sync evernote" than "sync dropbox"
because dropbox is just cloud but, evernote is note and cloud. and outliner is not file, NOTE!

plz, sync evernote like "cloud outliner" that sync evernote

plz!!!!

Would be nice if one could round-trip OPML files between CarbonFin and Outlinely (OS X) - http://glamdevelopment.com/outlinely

Right now whether an item is a "status" or regular node and if a status is "checked" or not is not be preserved between the two products.

Support printing directly from the app.

I have used CarbonFin for data entry on an iPad since Numbers is so primitive. For data entry, it would be helpful to be able to specify for each item the initial keyboard mode for adding text to it: numeric or alphabetic, and lower case, capital, or locked upper case, analogous to the way a spreadsheet cell can be formatted as text or numeric.
