Step 1. Download LÖVE from its website (~5MB). It's an old reliable open-source app; I'm not connected with it.
Step 2. Download tabs.love (28KB) then follow these instructions to run it. It's really a zip file and includes all the Lua source code needed to run.
Any line starting with --- (3 dashes) is a heading and will get added to the tabs on the right. Clicking on any tab will take you to it.
If you need help, just reach out any time.
Based on lines.love and my other Freewheeling Apps.
