I'm betting this isn't even on the radar as it may have been an intentional change to solve a scaling problem but: the timeline header no longer will display SVG or other image files it seems. That means any custom themes I've been working on became"broken" in a sense. For example, I can no longer get my custom MC 8ish dark theme timeline to look like this:
- MC 10 578 timeline header.JPG (47.45 KiB) Viewed 22153 times
Instead I have to settle for a solid color only like this:
- MC 10 579 theme image use changes.JPG (44.1 KiB) Viewed 22153 times
Not a big deal but slightly disappointing. It would be great if the option to use image fn = or tiled fn = for the timeline header returned.
