Look inside provided rc.lua.example.


After start sometimes there is black screen. Resizing termit window helps.

In options table 'tabs' field should be the last one. When loading all settings are applied in the same order as they are set in options table. So if you set tabs and only then colormap, these tabs would have default colormap.
