Please, add support for markdown in the description field.
Markdown is a fairly simple and widely used markup language, especially in the area of information technology.
I think those of us who require more expressive richness in the description field would benefit greatly from the addition of markdown support.
Those of us who are accustomed to using it will benefit immediately, but I believe that those who are not, with a little effort, can quickly incorporate the benefits of this tool.
If markdown support is incorporated, a global configuration item could be added to enable or disable it.
Even better would be to have a switch that indicates the activation of the functionality for each calendar individually.
