Summary:

• updated UI: added tabs in category view, improved search (google gesture search removed temporarily)

Skip:

Done:

• refactor the code in PR Refactor (separate menu, providers; rm ZipDownloader) #49

• use UUID so updates can be performed?! fixed in add guid for icon entries #51

  • e.g. store zip file + hash, check hash & extract to data dir on first load.
• search widget is crap (the one used if Gesture search is absent)
  • this should actually use standard search functionality plus fast scroll

  • display important icons first (!)
    • TODO: in future may allow to mark an icon as important!
• describe spc colors in docs: en
• updated a couple of icons...
• once categoty selected - hide not important actions, so more space is available for icons and UI is less overwhelming, with tabs etc...
  • leave only: search, maybe info..?
• optional: ease the dependency installation
• update the pics
