* ! Port all of Spark Reader's deconjugation rules https://github.com/wareya/Spark-Reader/blob/master/preferences/underlay https://github.com/wareya/Spark-Reader/tree/master/src/language/deconjugator
|
||
* - Fix katakana-hiragana matching (only happens in lookups right now, not display generation)
|
||
* - Definition priority handling (prefer words with any commonness tags, shorter deconjugations, expressions, non-archaic/non-obscure words, high frequencies)
|
||
* - More configurability
|
||
* - VNstats frequency data
|
||
* - Load deconjugation rules from an advanced setting, with a reset button
|
||
* - Work with text input fields
|
||
* ? List definitions of shorter text strings if they're not pure kana (in addition to main definitions)
