问题
First, I create new branch. Then, I add a new code line in my class. Intellij shows on the left with a different color that I added a new line. Then, I commit my code. After this, IntelliJ no longer shows that I added new line on the left. I don't want that.
How can I configure IntelliJ so it would show all the changes that have been done, compared to, for example, another branch or commit from before?

Unfortunately having diff markers in the editor with respect to some earlier commit is not possible right now in IDEA. Here's the ticket in JetBrain's issue tracker:

Changes with different color as you found only show the changes which are not committed. After you commit changes, there won’t show the new lines on the left (also as you found) since there is no changes need to be committed.
If you want to compare the changes which have already committed, you can select a commit and then show diff. Detail steps as below:
Version Control -> Log -> select a commit -> show Diff.
Then you will get the changes by compare with the previous commit.
