Personally, I think that the Note feature of Toodledo is pretty retarded -- as it is only plain text.
In an effort to make this (MUCH) more 'robust', I thought that it would be pretty interesting to create OneNote link(s). Imo, OneNote is a VERY useful & rich environment -- which I use endlessly for LOTS of stuff. However, I am not very keen on OneNote for tasks -- including (in particular) its links to Outlook tasks.
The following hyperlink taken from OneNote works if you paste it in the Toodledo Note field:
[The (real) OneNote hyperlink has 3 right-slashes ("onenote:///C:\...) -- but the 3-right-slash link doesn't work until you remove two of them.] As it stands, this link is pretty messy: it brings up an open dialog -- & throws error message(s) at the end. But, it WORKS.
I'm sure that some of you guys who know more web coding than I (the level of which is HIGHLY rudimentary) may be able to clean up the operation & structure of this link.
