same for Android, the task summary page is completely unnecessary, one can go straight to the edit task page, this will save so many clicks!

consider for example adding or removing a tag to existing tag:
1. click on task
2. click on Edit button
3. click on tags area
4. click on selected tag (to remove) or empty checkbox (to add) tag

it could be isntead:
1. click on task (completely skip the second screen)
2. click on existing tag (to remove it)
