I am curious to know that if it is possible to install TinyMCE editor in discourse because the default disocurse editor is very limited editing facilities and I want to avoid formatting my test with HTML.
Unfortunately, the composer is heavily customized and reliant in Markdown in multiple ways, such that I don’t think that that will work at first glance.
Format with Markdown, BBCode, or HTML.
Replacing the editor would take at least a week of work from someone who knew the code intimately. If you were learning it from scratch, several months to a year full time.
