Searching: unfortunately GitHub is actively preventing search engines from indexing editable wikis (<- please upvote). There are third-party crawlable mirrors (e.g. https://github-wiki-see.page/m/ocornut/imgui/wiki) but Google is doing a poor job surfacing the information. DuckDuckGo or Bing may occasionally do a better job. You can also use GitHub search bar above.

About the IMGUI paradigm

Dear ImGui is one possible implementation of an idea generally described as the IMGUI (Immediate Mode GUI) paradigm. The Immediate Mode GUI paradigm may at first appear unusual to some users. This is mainly because "Retained Mode" GUIs have been so widespread and predominant. The following links can give you a better understanding about how Immediate Mode GUIs works.

Another notable uses of IMGUI paradigm include Unity's own IMGUI widget library, often informally referred to as OnGUI(), which powers the Unity editor and its extensions. This library is unrelated from Dear ImGui. The IMGUI library used by Unity has in the past received mixed feedback from its users, presumably because it may have been perceived as a potential candidate for game-facing UI solutions, which it doesn't excel at. However Unity has since provided separate libraries to tackle that case, and their IMGUI library is still very much in use for the Unity Editor and has been its UI backbone for the past 15+ years.
