Tweaks are small adjustments that can make a big difference. Sometimes, however, we may want to convey the same meaning without using the word "tweaks." One possible alternative is "modifications," which similarly implies making changes to something. Another synonym is "tweaking," a verb form of the same word. To switch things up, we may also use "adjustments," which suggests improving or making minor alterations to a situation or object. "Refinements" can also be used in a professional context to indicate polishing a design or idea. Finally, "fine-tuning" can be an appropriate synonym when a more specific or deliberate approach is required.
