Until the New timeline is usable (ie. when Shift + click/drag works for creating new tasks)
I'm still using Old timeline, and the font is both too small + unclear (bad kerning and soft rendering).
Is it not easy to change that font? (eg. to match the font used in New timeline?)
I'm pretty sure 100% of people who notice the difference will appreciate it.
I don't see any reason to continue supporting Old timeline view with a difficult to read font.
