# Emulator (Previewer) enhancements
## Release Summary
This release included a number of feature enhancements, user interface updates, operational improvements, as well as a couple of bug fixes.
### **ENHANCEMENTS**
#### Emulator Channel Parity (Generic Features)
When creating flows, the [Chat Flow Previewer ](https://clickatell.gitbook.io/flow/workflow-management/using-the-previewer)allows the flow-builder to preview and test their flows to ensure the flow functions as expected. The Previewer emulates to the flow-builder how the flow would be experienced by end-users.
We are in the process to ensure that all available features and functions are supported on the Previewer. With this release, we've completed Phase 1 which included "generic features", i.e., features that are common across most channels.
The new features that are now supported by the Previewer are:
* Sending and receiving media
* Sending and receiving voice notes
* Viewing images
* Playing videos
* Downloading files
* Sharing locations
* Character count (applicable to USSD and SMS channels)

***Note:***
* "Sending" is from the Chat Flow bot that was built to the end-user so that the flow-builder can visualize what and how the user will receive the file
* "Receiving" is for the flow-builder to mimic the end-user by sending media/voice/location inbound (i.e., the Chat Flow bot that was built is receiving it)
* Viewing images and playing videos are for the flow-builder to test that media is working correctly
