Wordpress plugin customization needed

Hi freelancers, I have a Wordpress website that uses a plugin named xCrud. ([login to view URL]) I use this plugin to have a Datagrid for each user that lists important information particular to each user (where current username matches a field in the associated database rows) as well as a button in each row to download a PDF version of the information. Can you make following fixes? 1. Reduce loading time by not pre-loading base64 encoded blob data in xCrud query. Need to get the base64 PDF with a lookup method based on the current record row ID when clicking download button instead. 2. Fix an issue with mobile popup blocking. Right now, it needs to open a popup window to generate and open the PDF. While this works fine with desktop browsers (as long as popups are enabled), I need another method that can work on mobile devices. 3. Resolve 'Download All' field location/style with CSS. It would be good if it looked like the existing xCrud search field. 4. Add some new 'Download All' functions to allow users to download all by name, or just download all that have not been downloaded yet (currently downloaded record marked with a bit = 1, not downloaded the bit = 0). Waiting for your bids.
