Hello,
when commiting changes, new files and delted ones are marked green or red and have an icon before the file path. This icon makes it pretty hard to read all the changed files, because the file path text is intended. Either give the option to remove those icons or make the icons disappear, so all the files are aligned and start at the same vertical line.
For a small number of files that are changed, it is acceptable, but when you have more files and you want to skim the changed file paths, it get’s pretty hard. And isn’t a background color change enough UI-wise?
Besides that: I love Merge <3
