When importing URLs to multiple projects, the 'suggested' amount to import per project is calculated incorrectly.
To clarify, this is done from right clicking a project -> Modify Project -> Import -> URLs -> From clipboard
For example, when importing 1 URL to 10 projects, the suggested amount per project is 0 URLs. I guess this is because it simply divides 1 by 10 and rounds to 0.
Another error occurs when importing a number of URLs which is not divisible by the amount of projects, it will round the number to import to a number which works, but the total amount imported would be less than the amount the user is trying to import.
An example would be importing 1000 URLs to 3 projects, the suggested amount would be 333 per project. So 1 URL would not be imported to any project, as far as I know.
