You really think so? This is really my biggest issue with Dear ImGui, I think it just looks awful. The design is just not great, and stuff like text rendering has been terrible in every Dear ImGui UI I've seen. Especially on macOS, the native applications there really make ImGui stuff look pretty crappy. Electron apps also generally speaking just look way better, IMHO (Electron has other issues obviously, but the ones I use regularly look pretty good). Like, imagine VSCode or something with the graphical style of the screenshots on the GitHub page.

Maybe you can customize it and make it look great, but the "out of the box" experience is just... oof.
