+### An app a Bot cannot use yet asks once per turn
+
+When a Bot's call to an unconnected app was refused, the Bot often also asked to show that app's
+card, and the conversation drew the same Connect card twice. Each app's card is now drawn once per
+turn; asking again in a new message can draw it again.
+
+### The Computer panel shows the Bot's screen when it opens
+
+Opening the Computer panel beside a conversation could leave it on "Waiting for the Bot's screen…"
+while the Bot browsed, because the panel slid in from off-screen and the screen counted as out of
+view for as long as it stayed open. The panel now starts showing the screen once it has opened.
+
 ### Plainer words, and one word for each thing
 
 OpenBot now says **Bot** everywhere a person reads it, where screens used to mix Bot, agent, coworker
