export_slices plugin for Aseprite
This plugin adds a new command that allows you to export slices as individual image files.
This plugin uses aseprites CLI --split-slices option to export the files.

Download the extension from the Releases tab.
Open Aseprite's extensions menu Edit->Preferences->Extensions and click Add Extension.
Select the export_slices.aseprite-extension file and that's it.
Create your sprites and slice them appropriately. The name of the slice will later determine the exported filename.
Here I created a few simple 16x16 sprites, each slice gets exported as an individual file:
Click the new option in File->Linus045 Plugins->Export slices as individual images.
A Dialog with text entries will appear.
The first one specifies the .aseprite project file that contains the slices.
Simply enter the path to the project file or click the button next to the entry field to use your system's file selector.
The second text entry is the path to the output directory. As of now the aseprite plugin API does not have a dialog element to select a directory directly via the system's file selector. You can either enter the path manually/paste it in or use the file selector and select any file inside the output directory, the plugin will automatically use the file's parent directory as output directory.
The third text entry specifies the output file format.
It is directly passed on to the --save-as CLI parameter.
The fourth text entry is used for custom CLI arguments see Aseprite CLI documentation for more info.
After pressing the Export button a new dialog appears with the command to execute.
This is simply to verify everything or if necessary fix mistakes.
Normally you can just press Confirm and the plugin will now execute the command to export the slices.
Afterwards an output dialog will open up showing the command output.
This script actively executes the Aseprite with CLI argument --split-slices and passes in the project path and output directory.
