Important Update for InDesign CC
Adobe has just posted an important update to InDesign CC. This should fix some of the performance problems that have been reported on user forums and elsewhere. It will update InDesign CC to version 9.1. (There is also an update for InCopy CC to version 9.1.)
If it doesn't show up right away, quit out of Creative Cloud Desktop (choose Quit Creative Cloud from the flyout menu on the right) and relaunch it to force it to check for updates. You'll first be asked to update the Creative Cloud Desktop application to a new version, then the update will be available.
It also installs the new Sync Settings feature already available in Illustrator CC and Photoshop CC. Note that this does NOT yet sync preference files. It syncs the settings listed in Preferences > Sync Settings, including workspaces, customized menus, glyphs, PDF presets and keyboard shortcuts.
Here are links to two InDesign CC Help docs for Sync Settings:
And here is the link to the release notes for the update to version 9.1:
