# Extensions

The concept of extensions was implemented almost from the beginning of the project. The extensions created over the years are extracted from the TagSpaces core and published in a separate [repository](https://github.com/tagspaces/browser-extensions) on GitHub. Almost all of them are licensed under the permissive MIT license, so feel free to fork, extend and improve them. TagSpaces supports three types of extension: perspectives, file viewers and file editors.

## Perspectives

The perspective extensions offer alternative view on the files in a given folder. Depending on the purpose of the folder you can set a different perspective which will be opened by default by navigating to this folder. Depending on you current [use case](/usecases) you can also easily switch between the perspective using the perspective switch in bottom right area of the app. If you what to tag and organize you photos maybe the [Grid](https://docs.tagspaces.org/perspectives/grid/) perspective will be your choice, if you want to present your photos to an audience the [Gallery](https://docs.tagspaces.org/perspectives/gallery/) perspective could be your choice.
