The local system-font support is really great and I use it daily, but I'm stuck on the one piece it doesn't cover: my client's brand typeface isn't a system font. Their guidelines mandate a licensed face, which we license properly, it's just not Arial or Georgia, and the only way I can get it into a layout today is to install it on this machine and hope the picker finds it.
What I want is to upload the actual .otf or .woff2 into the editor so it travels with the document and embeds in the PDF the same way the built-in fonts do. Right now I'm limited to whatever's installed on whatever computer I happen to be on, which breaks the moment I move to my laptop.
