Google Docs is the leading web-based Office Suite. And, because it’s web-based, you can use the tool directly from web browser without having to install any additional software. Just like regular desktop-based office suites — let’s say Microsoft Office — Google Docs is also capable to handle a complex document.

One of good parts of Google Docs is that it has an add-on repository which enable you to add more functions that Google Docs hasn’t had. Each add-on is grouped in 5 categories from Business Tools, Education, Productivity, Social and Communication and Utilities.

This article is going to show the top 6 simple Google Docs add-ons but helpful enough to assist you doing your documents.

Great question. To apply a new font in Google Docs (other than default options) you will normally need to click 2-3 times. Sounds trivial but if you extensively use the different fonts it can waste your time. There is a handy add-on that will help you to apply a new font easier than before. It’s called Extensis Fonts. With this add-on you can apply a new font with a single click. Extensis Fonts will open 1200+ fonts offered by Google in a handy sidebar.

This add-on will notify you every time other collaborators made some changes over the document. The notification can be customized to make it more convenient and handy.

3. Highlight Tool

As you know, Google Docs is not different to regular desktop-based office suites that lets you highlight some important words. Normally, you need to select the Text color option from the toolbar every time you want to highlight a certain word. With Highlight Tool you can perform the same task with a single click. More interestingly, you can add multiple customized highlight profiles and just need to click each of them every time you need them.
