[Feature]: Template-Like Components (Reusable Headers, Footers, Layouts, etc.)

[unicornpoopwizard]

Is there an existing issue for this?

• I have searched the existing issues

Summary

The current issue is: creating a custom header, footer, or repeated UI block requires manually duplicating it across pages. Updating one requires updating every instance.

Request:

• Add reusable template components (custom widgets / global layout elements).
• Allow these templates to be inserted into any page.
• When the template is updated, the change propagates everywhere automatically.

Why should this be worked on?

This dramatically cuts down maintenance effort and enables scalable app design.

@unicornpoopwizard , this is available as a feature on our paid plans. We have something called reusable UI packages, which allows you to create a combination of widgets (including custom widget), couple it with JSObjects and queries, and then introduce them as a single widget on multiple pages of an App or across multiple applications. Any change done on the package will be propagated across the entities that uses it. Hence this will reduce the need for manual duplication and lack of control.
It also supports Version Control.

@TharinduEpaz , since the above is available, we wouldnt be requiring contribution for this.
