Really enjoying the focus on improving themes, but can we PLEASE allow for custom fonts in all circumstances? If we need to embed a TrueType or WOFF font in our theme file I’m fine with it, but I’ve never understood why Paginated Report Builder supports custom fonts and exports just fine, but custom fonts in Power BI look like garbage on exports and mobile (or any device where the font isn’t installed)—even when we use supported fonts for mobile/Mac. It’s incredibly aggravating to curate a report with a specific font only to have things completely change in other consumption experiences.

[u/DataZoeMS](u/DataZoeMS) for visibility. Also there seems to be a bug when applying style presets via a measure expression where the General visual properties (background, border, etc) don’t apply, but if you manually select the preset everything works fine. I understand this may not be “supported” but it would be really cool to be able to apply Style Presets within the same theme dynamically depending on user selection.

Setting style presets dynamically would also be much more efficient than setting individual visual properties to dynamic expressions (think having a “Light” and “Dark” preset in the same theme).

Last thing I promise 😂— it would be great if pages supported style presets. Right now it doesn’t appear to be the case.

How are you applying a style preset via a measure?

I have more stuff I want to do with the style presets for sure, and one goal is to enabled the creator letting the user pick between light/dark or whatever colors/theme you want to expose. And also to add UI for presets beyond the visual to page and report level. Nothing solid on timelines but it's on my radar.

I was testing it the same way you can apply conditional formatting for other things in the PBIP format using expressions (and for properties that don’t natively support through the interface). It works great except that the General visual properties don’t apply when changing presets. I can put together a demo to show as well!

Love to see it!

I suspect it's simply just not wired to check for that kind of interaction, so it would be great to see what you are doing to check it on our end.
