Stash Tab and Merchant Tab conversion

Ok, so the Merchant tabs aren't as what I expected:

- Didn't know about the lock in time,
- Didn't know about the gold coin cost involved, also
- Didn't know it requires users to 'talk' to Ange to access it!

Why can't you just leave it in the Stash box? It is not that hard is it?
Now I have transferred all my available stash to merchant and I can't go back, which is really fraustrating!

GGG, please add an option to let us convert it back.
