@manhtai please take a look, if everything is okay then I will polish the UI and finalize this MR

[manhtai]

@dmtri The MR looks great, I have some points to discuss though:

• Should we add another state (edit mode / view mode) to hide the function source code, because most of the time we needn't see it?
• Should we watch the change of input and apply the function immediately instead of hitting "Run" every time?

Again, nice work 💪

@manhtai

1. Yes, I agree
2. I'm not sure about this. It might crash the app when users are typing incomplete/erroneous code and they don't intend to run it yet. I could handle Enter keypress to save mouse movements probably :D
   Cheers!

@dmtri

2. I meant when in view mode, a wrong function / argument will output an error message anyway. No way it will crash the app 🤔

[dmtri]

@manhtai I see, watching argument changes in view mode is reasonable but watching function changes in render mode feels kinda wrong to me (user might not want auto run on every change) 😅

[manhtai]

@dmtri Yes, when in edit mode we shouldn't let the function run with every change, but when in view mode it is reasonable, just like every other built-in one ;)
