[Feature] Ability to customize the order and name of dictionaries

This app has been beautifully done. I'll just give out 2 feature requests to consider:

1. I use multiple wikipedia and wiktionary dictionaries for each language and for example my simple wikipedia and full wikipedia slob files have the same title "Wikipedia (en)", which makes it impossible to differentiate them from each other. One solution would be to have the ability to edit the titles of each dictionary.
2. The ability to pick which source to prioritize when the same query is found on multiple sources. I'd imagine that this might be trickier to implement depending on how the search works.
