Wow, you’ve created a TyControl for every LCL-control, and they look really good. We can trash all other controls and use this.
I spotted a bug: when you add a TyControl to a form, the design-time package `tycontrols_dt` gets added to the project as well; that shouldn't happen—the runtime package is sufficient.
I would rename `TyHtmlLabel.Html` to `TyHtmlLabel1.Caption`.
In any case, they look really good.
