Browse tags and their relations while filtering questions [feature/tag-browser]

[tdeekens]

A controversial feature

Architecture

• Collection view will hold all the tags (initially all tags ordered by occurance)
• Footer will show number of questions matching selected tags
• Header will contain search bar holding filter-phrase in text form
• The tag-browser will allow browsing a tag's relation in a n-1-only fashion as such we will not limit the relations to the whole set of pre made selections but only to the last selected one.

Interaction

• Tags in collection view will be reloaded with new tags upon a single tap on any tag on screen
• Search bar holds tags which can be added as filter (as in questions view) by double tapping on a tag
• The footer will contain a view indicating the number of questions still matching the current filter (selected tags in conjunction), tapping will load the questions view with filter
• Navigating through the screens shall be enabled by swiping on the main view
