Suggestion: make attaching pdf to transactions possible

The use case for this is: with some bills, a pdf is attached. Currently it is not possible to attach this to the payment transaction, only image files can be attached.

If the pdf is one page, I can convert it to JPEG and attach the result. This is somewhat inconvenient, but I can live with it.

If however the pdf is multi page, which occurs, I am at a loss.

Please consider making it possible to attach a pdf to a transaction and either present it natively in Manager, or launch a system pdf viewer with it.

You are using the wrong feature. The edit screen allows for image posting (not attaching) so it displays in the tab-listing. However you can attach as many PDF, images, docs, etc to the view screen of the payments, receipts, invoices, etc. See https://www2.manager.io/guides/9817 and bottom of screenshot:

Thank you, that does it! Clean and easy.
