Make selecting/managing tasks by labels like selecting/managing by projects.
Now selecting tasks by labels is very unusable in web app, because one must enter a text query in the search field or click the @-button and etc...
I suggest to make using tasks with labels like in android app. User need be able to choose a view: 1) tasks by projects, or 2) tasks by labels (like in Android app).
Accordingly (and it is important), if in a current view there is a selection by any label, the adding task function should works with automatically adding the current label to the new task (like in Android app).
It all is very important for users working with labels insteed projects. Now web app is unusable for this scheme.
