* change getNotifications to use filter

* remove temporary comments

* add an option to turn the FilterBar off in settings

* fix showFilterBar data type to boolean

* fix eslint errors

* add English and Polish translations

* allowed filter bar overflow to accomodate for longer languages

* fix mispelled translation key

* add unified CSS look
