Hi Mike
Yes that would part of the implementation, some changes in the css
But on top that to name a few, we also need to actually code the logic to differentiate whether the website it is currently being called from the Webview or desktop browser to trigger the css changes.
We also need to add a setting button to make this feature as options which will definitely requires changes on both end. Because other user might not prefer this as a their default.
These are just to name few of the changes I can think at the moment, but really the complexity of this feature really lies in the implementation it self and ensuring it doesn't break other part of the app.
If you think is a good idea and would greatly benefit the community as whole, I would highly recommend you to post this in our Feature Request

We will definite take it into consideration if this gain a lot of traction/interest from the community.
regards,
