Hi @Spencer ! Nice to see you would like to switch to Webstudio. I made the switch one year ago and I'm falling love to this tool I use everyday.
Here are some answers to your questions:
1/ Global component. It's bot live right now, but it's on the roadmap (I think it's for 2025) :
https://github.com/orgs/webstudio-is/projects/112/ Finsweet Attributes is not compatible with Webstudio but I would be interested to work on something similar for the community. Maybe some has already started working on that.
3/ Webflow Copy Paste. Be more specific and share a link if you need some help.
It's not my favorite feature because Webstudio and Webflow are not exactly the same tool. So in Webflow you have to deal with classes and Webstudio you have to deal with tokens. I recommand you check "Craft" the Webstudio Style Guide who can give you some best practices.
https://docs.webstudio.is/university/craft4/ Indeed, it's not possible to add image on Airtable. But it seems the feature is coming to Baserow. To feature has already be develop on the develop branch on Github but it's not merged on main. I don't know. I would be nice to contact the support in order to know why. I use Baserow for some project and it's working well with Webstudio!
Hope theses answer help a bit to switch to Webstudio 🙂
