It is now possible to register a shortcut for launching into the notification bar. Many people may think that this feature is essential because this app needs to call in other apps as you type. Why was not implemented? The answer is because this app is Mushroom plugin.
Mushroom plugin is an additional feature used by the input method implements Mushroom. Therefore, launching plugins and entering the result is done by the input method, even if it is running other apps. It is not necessary that plug-ins can be run independently. Many such plugins has been published.
In Japanese users, Mushroom has been widely recognized. So, there are many input methods that implement it, and there are apps that just launch plugins without the input methods. In addition, such input methods have been installed at the factory default into some models (ex. japanese Xperia arc.)
I expected that SymbolsPanel would be used with these apps. But it seems difficult until that Mushroom is recognized more. Therefore, it is now that SymbolsPanel itself can set the shortcut into notification bar. Still, I recommend to use the input method that implements Mushroom. It is very useful.
By the way, the default settings of SymbolsPanel 0.9c is at same place as before.
