I can't organise my glossaries. I want to move them around subfolders.
I guess this is what you will do when you implement cut and paste ?
Exactly. The Cut & Paste feature should take care of this. In the present version, Cut doesn't work but Copy & Paste work for terms. So if you can't wait, you can reorganize your words by recreating the folders (that's easy to do), copy and paste the terms in the newly organized folders. Once you're done, you can then delete the obsolete glossaries with the red X button.
I also would like to be able to sort glossaries and folders.
I've discussed this issue previously in this thread with Kurochka, if I remember well. I don't think this feature is essential. The folders and glossaries are already sorted alphabetically. I could add 2 buttons (arrow up, arrow down) to translate a tree item from one position up or down but this would burden the Glossary Manager's interface too much, IMHO. Because of that, I suggest you to prefix the folders and glossaries titles that you want to be sorted in a specific way with numbers like 01, 02, 03.
When I don't select "Show all glossaries" and specify "Language1" > "Language2" I think I should still see all the folders, even if they are not Language1 or Language2.
To see a folder when "Show all glossaries" is disabled, the folder must contain a glossary with some terms in the language specified in "Language1 > Language2". If you think about it, it makes sense. What's the need to show an empty (or irrelevant) folder? Most of the time, you don't want to see it. When you do want to see such a folder, that's where the "Show all glossaries" comes handy so you can insert words in it. I think that this behavior is what most people want, like 98% of the time. I may add a preferences setting to change this default behavior in the future but I'm not convinced that it's a good idea.
I think each glossary should have some notes to explain who made it, where it comes from etc. If you change the glossary title label to "Title" then there would be room for an (i) icon which could be tapped for more information.
This is on the todo list.
When you edit an entry, it would be nice if there was a way to navigate forwards and backwards to other entries.
I will put it on the todo list and consider it later.
The menu "Edition" should be "Edit", in prefs "Digraphes" should be "Digraphs" for the English UI.
I will update the strings shortly. Thanks.
