A few improvements were done when your verb is wrong. Now, if an accent is forgotten, search list displays in priority verbs with accents. That way, you do not have to care with the correct accents.
If you forget a h at the beginning of the verb, you can still try the same spelling with a h by clicking on the new button "Try with a h". Also, you can try the same verb without h if you put one.
And last but not least, if you really think your verb exists, you can click on "conjugate anyway". This option conjugates a verb without checking if it exists. Of course, your results might be strange if your verb does not exist and worst is not finished by -er or -ir. Anyway, you will have a good idea of your verb conjugation.
