"There are no kinetics for this entry." message could be more friendly/helpful.

[rwest]

This kinetics search shows "There are no kinetics for this entry." without making it clear that it's only because the reverse rate cannot easily be calculated by the website. In fact, there are kinetics available, in the reverse direction, by simply clicking on the search results.
It might be worth trying to get it so we can reverse the rate of a sticking coefficient, but this issue is mostly about the message shown on the website. It could be more helpful and explanatory.
