Custom transition-timing-function values

From old feedback: Custom transition-timing-function values | Cwicly

Option to enter custom timing functions for the transition property

In addition to that:

Currently it is not possible to enter variables or CSS calc functions into the transition delay field.
Useful for more advanced stuff like staggered transitions and also saves a lot of CSS instead of creating multiple Relative Styles just for transition delay purposes.

So both, transition timing function and transition delay, could feature an input with no restrictions.
I understand the way it currently works is most likely to prevent errors and hopefully this gets resolved at some time, also with other fields that only allows certain values.

Hope that makes sense.
