The Markdown plugin editor has a "Preview" tab where the document is rendered as HTML. I use a JEditorPane with HTMLEditorKit (source here).
1. This component seems to be quite buggy (corrupted display when scrolling, things like that) ... Does IntelliJ API provide a better way to render HTML ?
2. (if no answer to question 1) For some reason, it does not even work anymore with IDEA 10.5 EAP (106.330), the editor is replaced by this message: "This view is not available until indices are built" (seems to be a DumbUnawareHider).
Any hints on the subject ?
