The operating system you are using. Android 10 on a Galaxy S9
When adding a task in the desktop app in the editable column when you press enter it automatically adds the - [ ]
When you press enter in the Android app you have to always type the - [ ] which is obviously quite tedious if you have many things to add especially on a small phone screen keyboard.
Is there an easier way to do it? It is too hard to work with on the Android app when you have to keep typing - [ ]
Depending on what keyboard you use on Android, you can make a shortcut workaround. For example on Gboard I've assigned the shortcut td to write - [ ] for to-do.
And others, for example, iml for image link to write , hl to write *** for horizontal line, etc. Using shortcuts that make sense to you.
