Other Features

Explore has various new features, the most important being a new menu called "Explore". Other non-block improvements have been made in more recent versions.

Explore menu

The Explore menu has the following options. Most of the options are updated using info from the cloud.

• Check for updates: Checks for new versions of Explore.
• Current Development: Discusses current development of Explore.
• Explore community: Lists members who have signed up for the community (see Join community).
• Find member: Finds a member in the community.
• Join community: The Explore community is simply a group of people who use Explore. By clicking this button a user adds their username to the list.

The rest of the options open certain URLs.

New Plugins Feature

Explore 3.4 and later has a new feature called plugins. Plugins are change sets that developers can make to be added to Explore. People who use Explore can use the new Plugins menu to find plugins and install them to get special blocks/features.

Malware Protection

Explore, like most programming languages, has many useful features that can also be used to create viruses. There will be a malware protection feature in Explore 4.

Windows Installer

During development of Explore 3.3, jueschnei began working with powerpoint56, and created a new Windows Installer that is still in active development.

The installed version of Explore by jueschnei comes with many helpful new features. It automatically keeps Explore up to date, and has its own Explore2EXE converter. Recent development has been focused on the Explore Store, which will let users share and browse projects, plugins and more.

Future Development

There were plans for a version 4 of Explore. However, no update on this has been given since its announcement.
