Thank you,

Under consideration :) Yes, I still use PagePlus because I have it and still useful. I can open existing files, but I cannot open them in Affinity. That's why I want to keep it.
I will test PowerPoint later too. Affinity is intuitive because it has round edge feature compare to the older Page Plus. PowerPoint has a great equation editor.
I'll ask Rhino guys if SVG to clipboard is exist.
