Select and manage multiple games

[ZashIn]

Problem description

Currently only one game can be selected / managed at a time, while at least the following actions could be done for multiple games at once:

• changing categories
• updating
• uninstall
• (install)

These actions are all supported for selected game in Steam, too.

Feature description

Select multiple games by adding the following features:

• add a checkbox on the icon (grid view) / in front of the entry (list view)
• add hotkey / modifier keys to select:
  • CTRL + LMB: add single game to selection
  • SHIFT + LMB: select range
  • CTRL + A: select all / none of the currently filtered games

Manage the selected games with these actions:

• change categories
  • check only common categories
  • use e.g. a grayed out checkmark for categories used only by a some of the selected games
• update: queue under downloads
• uninstall
  • add some kind of queue / process for each uninstalling game
  • option to cancel the whole queue
• (install: would require shared install dialog for location etc., otherwise similar to uninstall)

Alternatives

• categories: edit config?
• updates: use auto updates
• uninstall: remove folders & rescan?
