Конфигурации

Индикатор настроен через два json-файла, хранящихся в домашней папке пользователя каталог

~/.files_indicator.json управляет пользовательским интерфейсом, длиной записей в меню и максимальными номерами в меню последних файлов.

{
    "name_length": 30,
    "max_items": 10
}

~/.pinned_files.json управляет списками закрепленных файлов и папки. Каждый элемент представляет собой список / массив.

{
    "dirs": [
        "/home/xieerqi/\u56fe\u7247/Wallpapers"
