If you want to use InputText() with std::string or any custom dynamic string type, use the wrapper in misc/cpp/imgui_stdlib.h/.cpp!

As InputText() retain textual data and we currently provide a path for user to not retain it (via local variables) we need some form of hook to reappl

Edit a string of text - buf_size account for the zero-terminator, so a buf_size of 6 can hold "Hello" but not "Hello!". This is so we can easily call

Tip: use ImGui::PushID()/PopID() to push indices or pointers in the ID stack. Then you can keep 'str_id' empty or the same for all your buttons (inste
