Indeed, this is one of the crucial things that prevent Wappler from being the universal user-friendly nocode tool.
I made the same request some time ago, but it didn’t get attention.
Also need to mention, that there is another problem, that spoils the preview within the Wappler.
Pages within Wappler don’t get query parameters. There is my old FR about it. There are some workarounds, but it’s not convenient.
If Wappler will provide the ability to fully preview pages, it would be incredible!
