IntelliJ IDEA: Increase size of bar on the right side of editor

Question

I'd like to increase the size of the bar on the right side of the Editor in IntelliJ IDEA. It's simply way too small for my taste.

It is the bar where the warnings or usages are displayed.

P. S.: The bar is called Error Stripe.

Answer 1

I agree, the scrollbar is far to small, and hard to see.

Another option you could try is installing the "CodeGlance" plugin which adds a full view of the code and makes scrolling far more intuituve.

Grab it from (as of 15-04-27) https://plugins.jetbrains.com/plugin/7275?pr=clion

Answer 2

Press Ctrl + Alt + Shift + / and select Registry... from the menu that appears.

Look for editor.full.width.scrollbar and tick the box on the right. The change should take effect after clicking the close button. The width of the scroll bar should be marginally wider, it's not a lot but every little bit helps :-)

Unfortunately this setting only affects the scroll bar on the right of the editor window. All the other scroll bars are unaffected.

For those that find transparency effects annoying then look for editor.transparent.scrollbar and untick the box on the right. This change should take effect after clicking the close button and restarting IntelliJ.
