[CentOS] Linux alternative to MS OneNote

Have been looking for an alternative to OneNote which will run on CentOS.

I've looked at Evernote, but it's support for Linux is emerging (supports Android, but not other flavors yet).

I've looked at nixnote, but it looks as though I might have to make from source. I can do that, but would prefer to find something in the standard CentOS repositories.

None of the other recommendations I've found out on the net show up in any 'yum list recommended-tool' runs.

Most seem to recommend getting an MS Live account and accessing OneNote in the MS cloud with a browser. I suppose I could do that, but would prefer my data stay on my CentOS box.

Any recommendations here?
