I am using the Neo4j Browser.
Depending on where you hover the mouse over a button with an icon, you get different hover text.
For example:
pin vs Pin at top
expand vs Fullscreen
button-refresh-arrow vs Rerun
close vs Close
neo4j-outline-32x vs Graph
Text2 vs Text
app-window-code vs Code
This is only cosmetic, but gives an 'unpolished' feel to the product.
