A new option is available in Triddlers - keep lists of puzzles saved and load them in any time. Here is how it works:

Filter a list and sort its order, then - click on the icon .
A small window pops up and enables you to name the list. You can use your own language, foreign characters as well.

You can save up to 3 different lists to load in any time. You can clear old lists and select news ones to save.

Enjoy!
