This is an alpha version that comes with an incomplete set of basic features and has some known issues. I will be constantly working on DebugStudio to make sure every bug is fixed and all designed features are implemented.

Features:

Add Many Breakpoints

Select many lines of code and hit F9 - a breakpoint on every line selected will be added

Always Enabled Breakpoints

Make some breakpoints always enabled to make sure they cannot be disabled

Display Hit Count Inline

See hit counts of all breakpoints hit inline

Set Hit Count Limit

Disable a breakpoint when its hit count reaches a specified value

Focus On Usage

Make lines containing usage of a variable stand out to be able to find bugs easier

Now you can use this feature also during design time

Enable/Disable Many Breakpoints

Select many lines of code and hit Ctrl + F9 - breakpoints in these lines should be enabled/disabled

Null Objects Display

See which objects are null as you debug

Boolean Values Display

See which booleans are true and which are false

Hit If $CALLER Contains

Hit a breakpoint only if the previous function's name contains/doesn't contain specified string

Create Data Breakpoint On Variable (C++ only)

Quickly and easily create a data breakpoint on a specified variable

You can configure the extension in the Options window:

You can turn every feature on and off one by one or all at once

Known issues:

- Display Hit Count Inline - sometimes hit count is not visible when there is a little space before the line of code available
