Usually when I need learning, I enable learning and keep both Frequent Pattern and Phrase List1 active.

Clarification: all learned phrases are stored then read by the Frequent Pattern plugin, so if you disable it, the learning is still active, but learned phrases aren't used for autocompletion suggestion. If you disable learning and enable plugin, the learning stops, but learned phrases are used for autocompletion.

The frequent patterns (learned phrases) are kept in a database "wdb" and "fpdb" files. These can't be open in notepad. I am still struggling on whether I should use a text file to store frequent patterns.

using database:
pros:
I can keep contextual, meta information about the phrase learned, to suggest it at the right time and better prediction accuracy. Manage the phrases for the user automatically.

cons:
User can't read the phrases unless I build an interface for their introspection.
more performance, memory overhead

using a text file:
pros:
User can add, edit, delete a learned phrase

cons:
can't keep contextual information, that would make the format complicated
it defeats the purpose of the software, as the users are occupied with managing the phrases, which I try to do for them.

and u r right, it's good to let user changes the file names.


About the position of the tip window. I don't know how to get it right on all systems. So I set the position a little to the right. as you type 'posi..." you probably should have completed the phrase before the tip window starts to block your typing.

 8) well, remember 3 things:
(1) +/- in front of variable is a unary operator that changes the sign (as in maths)
(2) plus plus = plus, minus minus = plus, plus minus/minus plus = minus (as in maths)

To me these are rules that were established long before programming language, since the time of Greek. It's C which changed the rules, and that's why I and some had had a hard time learning C in school, Python is more natural to me.

(3) There is usually only one way to perform certain task (Pythonic principle)

It is not hard to understand Python's choice and figure out the answer to the TEST.
