I cannot find any dedicated forum for Parley and so I was wondering if anyone can help me with the following?

If you download a collection and decide that you do not want it how do you remove it? The method seems to be click on the download collection again, find the item in the list and then click Uninstall next to the same collection but that does not seem to work. (there is no Apply button)

I see that three languages may be shown on the same screen (from the graphic on the website home page). How is this done? The user manual misses this. For example I would like to have three columns - English language, romanised Thai and Thai language characters. How do I set that up?

I cannot find hidden any settings / configuration file for this application .. where may that be found?
