I’m considering getting a Boox device for personal use and one of the things I do quite often is work with PDFs. On my work tablet, I use WPS Office PDF a lot for reading, annotating, filling forms, and occasionally signing PDF documents.

How good is the PDF editing in the Boox devices in practice? Can you easily add signatures, fill forms, make annotations, and save the changes back into the PDF without issues even for large documents?

I’m not looking for a full desktop-level PDF editor, but I would like something reliable enough for everyday document work.

I'm finishing out the interior of a 40x60 steel building. The insulation is done, and now I need to figure out climate control. I want to avoid hanging a loud, ugly gas heater from the ceiling. I'm thinking about putting in a split system heat pump so I can run ductwork down the center. I found a costway 4 to 5 ton 17-17.5 seer2 ultra-low temperature heat pump system that claims to work efficiently even in freezing weather. Has anyone used a cold-climate heat pump to heat a large, open-concept metal shop? I just want to know if it actually keeps the concrete floor warm enough to work on in January.
