I've been wanting an extension like this for a while but never found something that met all my requirements so I made PromptMods, an AUTOMATIC1111 / Forge / reForge WebUI extension that adds customizable text before and after prompts with support for text stripping (like when you grab a prompt from PNG Info) alongside proper integration with Styles, Highres. fix and other extensions such as Dynamic Prompts, ADetailer and Image Browser.
