Bubble.io Mais Leve is a Chrome extension designed to enhance the performance of the Bubble.io editor, making it lighter and faster for developers. This tool allows users to easily add URL parameters to the editor or application preview, thus improving the overall development experience and facilitating debugging processes.

Key features include options in the EDITOR tab such as "defer_hidden_elements," which loads only visible elements, and "issues_off," which prevents error searches to reduce overload during development. The PREVIEW tab offers a "debug_mode" option that enables the Bubble.io debug bar for identifying issues during flow execution. It is important to note that applying these settings requires a screen reload, so users should ensure no ongoing activities may be disrupted.
