i would like to sponsor the fixing of this Okular issue which forces me to use proprietary pdf viewers to populate the PDF Form. In order to bring okular to a level where it can really compete with other products there are quite some PDF Form issues that need to be fixed. But let’s start with this one and see if this is a way that we can go. I can offer 25 € for fixing the issue payable to an individual person or preferable to KDE e.V. (for tax reasons ). I know that the amount is not enough for someone living in the western world, but it’s a start - and others can join this effort.
Hoping the best,
