* No duplicate records
* No empty text column
* No already annotated annotations
* Browser is not refreshed
* And single user session.
To reproduce (I did not check the minimal amount, but after 2000, it was ok and after 3000 not):
prodigy ner.manual mydb blank:en my.csv --label mylabel
Then I press 'a' to validate annotations (not necessary labelling anything), save every 10 inputs and make sure I don't go too fast, else the browser complains. After about 2900, I have "No tasks available".
I also tried to
go through 1000 data, CTRL-C to save. It showed 1000 added.
go through 1000 more, CRTL-C to save. It showed 2000 total.
go through 1000 more, after about 900, "No tasks available"
