Many thanx for Developer with the latest new v5.9 and url-scheme for Search on text / tags i almost delete all my smart lists and made an amount of repeating tasks with the internal url for searching for that certain tasks as alternative .
Like WaitingFor smartlist has been replaced with
goodtask3://search?keyword=%23wachten&view=1
Hopefully my last request autocomplete of tags in notefield will come in v5.9.1 or in v6.0 or later
