Thanks for the suggestion @danilopeixoto

Introducing a new user setting will be best to address this. I can provide pointers if you want to push a PR.

Hi @fcollonval,

First, thank you for the Mamba Gator development.

Is this the line to add a condition?

https://github.com/mamba-org/gator/pull/42/files#diff-4cb47daf968330dba84ee8069d23ca03354e3e77068181e77f055b61f3719cceR41

Adding a condition here, will prevent the Gator from loading packages in background?
Next loading events will happen just when using the Mamba Gator UI?

Indeed this is the one.

Yes

To add a user parameter, you will need to edit the settings json schema (something like fromHistory):

gator/packages/labextension/schema/plugin.json

Line 18 in 90be2e1

"fromHistory": {

Then you can modify the line:

gator/packages/labextension/src/index.ts

Line 48 in 90be2e1

Private.loadPackages(model);

like that:

-   Private.loadPackages(model);
+   if (settings?.get('<param name>') ?? true) {
+     Private.loadPackages(model);
+   }
