Q: I change the tense setting under Menu::Preferences but the drill is unchanged?
A: The preference setting does not affect individual drills, you need to customize a drill
by long clicking on it.
Q: How can I restrict/limit the pronouns used by a drill?
A: Long click on a drill, choose "edit", the select "choose pronouns".
Q: Why are the conjugated forms not translated?
A: This is intentional as there usually is not a very good correspondence
between the use of tenses in one language to another.
Q: Why aren't there more forms for the imperative?
A: In most languages the are only two genuine forms of the imperative
(2nd singular and plural).
The other forms are borrowed from the "present subjunctive" tense.
Q: How do I migrate my drills to the Pro Version or a new phone?
A: The drills are stored in a user accessible directory on the phone.
The exact location of the directory is listed on the About screen
(Menu:About) under Storage. Copying the files will transfer the drills.
Q: I get a broken drill error. What can I do?
A: Most likely the memory on your phone is going bad.
The app keeps several backups of each drill to deal with this. You can make them (in)visibile
To solve your problem, make the backups visible. Then remove the broken drill and rename
one of its backups to not have "[xxx]" at the end of its name. Note that renaming really just copies the drill.
