A few months ago, Gmail has changed its design. In its new design, they put icons on the new toolbar buttons, instead of text. Some people liked the new icon buttons. Others found words easier to distinguish. Sometimes, it also annoys me a lot.
After lots of feedback, Google has finally fixed this issue. If you want the old text buttons back, please follow the following easy steps.
Login to your Gmail account.
Click on the “Gear” icon on the right side, to open the Settings menu, and click the Settings link.
Find “Button labels:” option under the General tab and select option “Text” then save the settings by clicking the “Save changes” button under the settings page.
That’s it. Go back to the inbox to see the new text buttons. You can also switch to the new icon version whenever you want.
