I've noticed some minor issues in formation and options.
1. In Options dialog, when in Formatting you have created a custom format, its filename appears at the top of the window (after Show In Folder). Clicking on it opens the folder where the xml is placed. The problem is that it opens the folder twice.
2. In Formatting (custom format), i have the following settings:
a. Where\IndentConditions: True
b. Where\SpaceBeforeConditions: Space
Boost insists on adding a tab before conditions though instead of a space and the same thing happens in the fields at the "select" area. In general, all my settings are set to add spaces. Also, in SSMS options, under text Editor, all tab settings are set to "insert spaces".
