Frequently asked questions
Is the order of my lines kept?
Yes. The first time a line appears it stays in place. Only later copies are removed.
Are 'Apple' and 'apple' seen as the same line?
Only if you tick 'Ignore upper and lower case'. Otherwise they count as different lines.
Is there a limit on the number of lines?
No fixed limit. Lists with tens of thousands of lines work fine on a normal computer or phone.
