These are the two files I've pushed to Bitbucket from a Linux OS - same name, just different case formats:

TesT.txt

test.txt

However, once I cloned the repository into SourceTree on Windows, the two files ended up as just one file, but as if there's changes made by the other file:

Expected behavior: SourceTree should detect case-insensitivity problems as it has full control over the repository, it should know if there will be any filename clashes (either by explicitly knowing the filesystem or testing the filesystem by writing a file, then writing with a case-different name and check if there are any clashes.)

When this unintended file modification would occur, SourceTree should display a warning or offer some resolution (whether the problem is in the filenames, or the directory names, resolution could be entirely different)
