Interesting concept, and I think it has a good amount of potential! I would expand this and add a few things:1. let me add descriptions to the parameter names that show up in the bottom pane2. let me expand the top pane 3. let me add multiple commands within the same snippet that have the same parameters but are visually distinct4. separate different commands by an area for markdown5. add custom tag support 6. add syntax highlighting for other languagesbasically, I think you have the start of something beautiful and could easily turn this into the snippet manager that I've been looking for. the layout you have is clean, and simple and think adding a few of the above features could make this app really popular. I love the core functionality of being able to separate parameters and would LOVE a way to add descriptions to them so I can remember what the heck any given parameter is for.

That other review is bananas: SnippetsLab is the class of app I've been trying to replace for this purpose. cmdLab is targeted toward… commands, like ffmpeg, not code… snippets, like those of Swift. That's why the entire markup is {} and [] and the syntax highlighting is only optional and required parameters. I really wish this didn't appear abandoned. The only other trace I saw of it was a year-old YouTube video with no engagement. At least that's not three years old like the last update here, but <sigh>

Please do not install this as this is a fake app that is parading around as the authentic Snippets Lab app, and we do not know who it is that created it, as there is zero information on the developer and zero support. Their website doesn't even resolve to a real website. For Apple to allow things like this is beyond me, when they are so strict otherwise on every little design detail of their apps. Please save yourselves the keystroke hacks. DO NOT INSTALL FOR YOUR SAFETY!!!
