[Angelk90]

Step -1: Before filling an issue check out troubleshooting section

• Go to README.md#Troubleshooting

Step 0: Describe your environment

• OS: Kubuntu 21.04
• diff2html version: 3.4.11
• Using diff2html directly or using diff2html-ui helper: _
• Extra flags: _

Step 1: Describe the problem:

diff2html/src/templates/file-summary-wrapper.mustache

Lines 3 to 5 in 9ed73c7

	<span class="d2h-file-list-title">Files changed ({{filesNumber}})</span>
	<a class="d2h-file-switch d2h-hide">hide</a>
	<a class="d2h-file-switch d2h-show">show</a>

As you can see from the code above the texts are permanent, it would be possible to make it so that the end user can modify the texts as he prefers.
In case the texts are not changed, set the default one.

👋 Currently there is not direct support for this.
The closest you have is to override the templates using the flags described here.

If you are interested in contributing a feature feel free to propose a solution and we can discuss it here in the ticket and then you can move on with the implementation.
