Needing iOS multitasking / Split screen .... ASAP

This is the go-to app for all file management and productivity, but --> really need to get the multitasking update out soon. Paid upgrade or not - people want this app. PDFs on one side + Document writing on other; Video on one side + Notability study notes on the other; etc... There are workarounds out there but dont want to abandon this app yet.
