EXIF Data in one row / hide "show exif data" button?

[reox]

I want to display the (to me) four most important specs of a photo: Aperture, Focal Length, Shutter Speed and ISO. However, the theme is designed to only have three values next to each other using the col-sm-4 class:

piwigo-bootstrap-darkroom/template/picture_info_cards.tpl

Lines 242 to 276 in 83b6ad4

	<div class="row">
	<div class="col-12{if $theme_config->fluid_width} col-xl-10{/if}">
	<div class="row">
	{if is_array($metadata.0.lines) && (array_key_exists("{$exif_fnumber}", $metadata.0.lines))}
	<div class="col-6 col-sm-4">
	<span class="camera-aperture fa-2x pr-2" title="{$exif_fnumber}"></span> f/{$metadata.0.lines[{$exif_fnumber}]}
	</div>
	{/if}
	{if is_array($metadata.0.lines) && (array_key_exists("{$exif_focal_length}", $metadata.0.lines))}
	<div class="col-6 col-sm-4">
	<span class="camera-focal-length fa-2x pr-2" title="{$exif_focal_length}"></span> {$metadata.0.lines[{$exif_focal_length}]}
	</div>
	{/if}
	{if is_array($metadata.0.lines) && (array_key_exists("{$exif_exposure_time}", $metadata.0.lines))}
	<div class="col-6 col-sm-4">
	<span class="camera-shutter-speed fa-2x pr-2" title="{$exif_exposure_time}"></span> {$metadata.0.lines[{$exif_exposure_time}]}
	</div>
	{/if}
	{if is_array($metadata.0.lines) && (array_key_exists("{$exif_iso}", $metadata.0.lines))}
	<div class="col-6 col-sm-4">
	<span class="camera-iso fa-2x pr-2" title="{$exif_iso}"></span> {$metadata.0.lines[{$exif_iso}]}
	</div>
	{/if}
	{if is_array($metadata.0.lines) && (array_key_exists("{$exif_exposure_bias}", $metadata.0.lines))}
	<div class="col-6 col-sm-4">
	<span class="camera-exposure fa-2x pr-2" title="{$exif_exposure_bias}"></span> {$metadata.0.lines[{$exif_exposure_bias}]}
	</div>
	{/if}
	{if is_array($metadata.0.lines) && (array_key_exists("{$exif_flash}", $metadata.0.lines))}
	<div class="col-6 col-sm-4">
	<span class="camera-flash fa-2x pr-2 float-left h-100" title="{$exif_flash}"></span><div> {$metadata.0.lines[{$exif_flash}]}</div>
	</div>
	{/if}
	</div>
	</div>

But if you change it to col-sm-3, you get all the quantities next to each other:

Would it be an option to change this in the template? Of course, if you add exposure bias and flash, it will look odd and the 2x3 is then the better option. Of course, an awesome solution would be to check whenever 4 or 6 items are to be displayed and then use either a 3 or 4 column width.

Another thing is the button: If you restrict piwigo to the basic EXIF data, there is not much more to see in this button, just duplicated information.
Thus an option to hide the button would be awesome as well!
