Still trying to find NTHD and Dropbox.
I emailed the developer and he even said no
Maybe I'm misunderstanding what it is you want to do with NTHD and Dropbox. When I punch Output, Done, have open PDF selected, punch Start, up comes the "Open In..." box, and DropBox is there as an option. I click on DropBox and whoosh, the PDF is in DropBox. I know it works 'cause I just tried it (have never tried it before, mind you). I must be missing something.
I use NTHD almost exclusively for maths, very rarely for reams of words. Lately when I
do want to take lots of handwritten notes I've been using Noteshelf. Due to its excellent auto advance system I'd like to use Notes Plus but a few things about it annoy me.
I agree with jsh about practice.
I'd also say that it's been very useful to me to have more than one note-taking app on my iPad. I often have NTHD, Noteshelf, neu.Notes and Notabilty all going at the same time. I do the same with readers: Good Reader, iBooks, iFiles, iAnnotate. Switching from file to file with a push of the home button rather than having to move around in one app when you're juggling a number of documents.
I don't know what you mean about the blue dot in NTHD.
