Problem Definition

When a user switches branches in SourceTree in a repository with submodules, SourceTree checks the submodules by running git submodule update --init --recursive.

For repositories with a large number of submodules, this operation can take a long time. And thus, switching branches takes a long time as well.

Suggested Solution

Allow the user to disable submodule checks when switching branches.
(At the moment, this option is available for commit and push, i.e. disable submodules check before commit and push).

Why this is important

The operation of switching branches can take a very long time for repositories with a large number of submodules.
