Interesting idea. For sure these are not traditional "dictionaries", but translation dictionaries such as the Oxford bi/multilingual dictionaries and so on.

Regarding that, two things. First, if you have translation one way, having translation the other way is somewhat expected. Its what all book form translation dictionaries do as do Google translation services and so on. Fortunately, the Freedict site has many translation files that can go both ways on two languages.

Second, could we get an implementation of French-English/English-French?

For loading, yes, you need to load the files the mod uses into memory; you can't read from disc. But...you don't need to load them during logging in, which delays you getting into game when you have large files/databases. Instead, use Addon Loader.

Having the mod load "delayed" (see its documentation) will prevent lag prior to getting into WoW--especially for people running older computers--as the mod and its translation files are not loaded until the user is in the game. You can also specify different loading conditionals in the TOC of Dictionary.

Once you integrate support in Dictionary, you will need to point people to Addon Loader if they want faster logons. Once installed, though, users don't have to worry about it. Its supported by many (many) mods; several on the WowAce site, Curse, here and elsewhere. So people will get bonus use out of it.

For loading certain dictionaries, for sure if a user doesn't need them all, loading them all is a waste. But you can create options in the mod to load certain dictionaries only "Load On Demand" (separate from Addon Loader).

Put the dictionary files into separate folders with their own TOCs. Have the following line in the TOCs: "## LoadOnDemand: 1". Have the mod be able to find and load those files when the user specifies they want them loaded in the mod's options. Can also use Addon Loader to load the dictionary files separately.

I have some quick feedback for you. I like the concept, there are some things I would like to see. Great work btw thank you. Below is some wish list items as well as testing observations.

1. Window movable and scalable
2. Font choices
3. Parse selective channel(s) - ignore selective channel(s)
4. menu driven under Addons tab via interface options
5. The text seems to grow backwards? The newest text should be at the top. It seems to be the bottom text is newest.
6. Language selector via menu
7. Memory is up there.

Thank you for your contribution. This is very highly needed where we have so many intermingling languages. Thank you for this. I will test and provide feedback.
