Only Parts of a trello json imported - Script stops

[HDValentin]

The import works until a certain point.
The file has 800 Kilobytes.
I think it rans into a php timeout and stops the import.

The first list with 67 Tasks is completely imported.
The second stops around 110 Tasks.

I increased the php max execution time on the hosting. But it is not enough to import all elements.
Perhaps it would help, if you import in steps of maximum 20 Seconds and then restart with the next until everything is done.

Hello, thank you very much for using the extension.

Actually, the PHP timeout problem is already a known problem in the extension's operation.

Unfortunately, I don't have time lately to get around this problem, however if you want to submit a pull request with the necessary changes you will be very welcome.

Thank you for the response.
My programming skills are not good enough to do that sorry.

Sidenote
As workaround, it helps to split the boards into smaller lists.
But there is no possibility to move lists to another project.
