Firstly, I want to say that this plugin is amazing.
There are some problems that I faced with it, but I am glad I have been able to work around them. Here is one of them:
In math mode, I often have to write complicated expressions like \Gamma^{a}_{bc} but I am facing a problem here. To illustrate:
$$
a^{b}_{c} a^{b}_{c}
$$
but
$$
\Gamma^{a}_{bc} \Gamma^{a}_{bc}
$$
doesn't.
I was able to find a work around to do this:
$$
\Gamma^a_{bc} \Gamma^a_{bc}
$$
which does get compiled properly. This may be a bug?
