Make it easy to search tasks within a folder
When I am viewing a task folder and tap the search button, my intention, pretty much always, is to search tasks in the current folder, not to search all tasks. Not only does the app not behave this way, i.e., the simple search function that pops up searches across all tasks rather than the current folder, but it is ridiculously difficult to do a search that is restricted to one folder. Taps involved:
Search button
Scroll to expose Advanced Search button
Advanced Search button
Add filter rule
Folder
Modify
Desired folder
Save
Save
Add filter rule
Title
Type search text
Save
Search
That's ridiculous, especially since as I noted before, it should do that automatically, when the search button is tapped in a folder.
A good way to implement this would be to add an option to the quick search feature (which is accessed by pressing the search button). This option would limit the tasks being search to the current view (which could be a single folder, a context, the hotlist, custom view, etc.).
