Yes I am talking about the editor. The IPV5 TipTap editor allows HTML in forum posts/comments but there is no functionality to enable the same for articles or article comments.

God, I really hate that there is not a "source" or raw HTML mode like the IPS 4 WYSIGG editor had. I think there is a way to enable it in IPS5 for the editor for Forums but not for pages articles/comments (wtf?).

Sure, I'll send you a DM with a link containing some examples.

A lot of other users already said the same but the source mode is also very useful for my community as well. We post patch notes and use a GPT to format them nicely into our HTML/CSS templates. Is source mode coming back or probably not?

Fair. Could tot answer the question in OP please? Is there a timeline?

Is there any beta documentation for theming HTML/CSS custom theming on IPS5 yet? Without the marketplace we need to determine the feasibility of recreating our theme for IPS5. Considering the amount of features decommissioned, lack of certain features for Classic clients, and the lack of continued support for Commerce payment methods the only two things we’re really using the IPS suite for now are pages/blog posts and a basic stripe checkout with a better external stripe checkout that actually supports all stripe payment methods. Depending on the usefulness and viability of V5/theming were possibly going to consider finally saying goodbye to IPS after 10 ish years and create a basic CMS in Blazor or basic blog site.

Yeah, because Apple and Google know the value of creating a "platform" and empowering developers.
