A new version of Tools was added to project The Inbox:
http://source.squeak.org/inbox/Tools-ct.915.mcz

==================== Summary ====================

Name: Tools-ct.915
Author: ct
Time: 15 November 2019, 5:30:02.890005 pm
UUID: 326d55bd-8463-7e43-a517-e934932fb3a9
Ancestors: Tools-mt.914

Refactor ProcessBrowser nil checks again and move them into #stackListKey:from:. Also, use #browseMethod: in #browseContext to ensure the right version is browsed

Thanks to Marcel for the review!
