BossPrefs is updated today to v2.0.6b for firmware 2.0 only. This version adds some new features for hiding icons. This paves the way for Categories which BossPrefs developer plans to implement soon. Here are the formal changes:
Added missing file needed to detect running state of custom services.
Redid hidden icons GUI.
Added ability to hide appstore apps now.
Redid how icons are hidden. 2.0’s restrictions mechanism is used now to hide icons. This means that hidden icons no longer show up again on an upgrade of a package. The downside is, if you ever disable restrictions in the settings menu, (or enable it then disable it) all your icons will be visible again and you will have to hide them again. Note you should update poof (if you installed this) also. The two apps must be in sync if both used or hidden icons from one may not be able to be unhidden from the other.
