I wanted to change the padding around the search box but I couldn't achieve it. I tried to look in the CSS file but not much info is there. And I can see that there are multiple static values of height set in the constants/ui.js file. What is the right way to increase padding around the search box? And also what about rounded corners?

Problem:
ctrl+J is default in Windows Chrome for opening the downloads page. I know I can change it myself on the extensions page, but you might want to change it by default to accommodate those users.

Describe the new feature you are requesting
When you are adding mods to your instance, it would be cool if there was a button to open the mod's curseforge site.

Describe alternatives to this feature if Applicable
Maybe show more options when right clicking the image of the mod when you search for it.

Additional Inforomation
It would be cool to share mods with other people work

I left Median XL\resources_app.asar, and it didn't remove it.

Investigate and fix. Should be easy.
