@c_schmitz : i make a fork for this client , but are you OK for such feature in 4.X ?

Sure, fine for me. But maybe a bit more generic, like 'download_base_name'

i think too of some other part :

1. Tutorial «Welcome on %ToolName»
2. System Information : «LimeSurvey version» , but this one is only for super-admin, then less needed, maybe keep it.
3. About Link : support and donate ? I replace/replace it in fork but , OK too ? (else : JS is OK for me)

Then in config-default:

$config['toolname'] = 'LimeSurvey';
$config['download_base_name'] = strtolower($config['toolname']);
$config['manual_url'] = 'https://manual.limesurvey.org/';
$config['donate_link'] = true; // Just show or hide
$config['home_url'] = 'https://www.limesurvey.org/';

And maybe $config['donate_link'] is forced to true for forced super admin ;)

PS : maybe some can be moved to admin theme

<config>
    <metadata>
        <name>PersonalTheme</name>
        <presentation>A adpated tool for surveys</presentation>
        <manual_url>A adpated tool for surveys</manual_url>
    </metadata>
<config>

Like you prefer :)

@DenisChenu: Are you interested to make PR in develop branch?
At least for export filename to start with.

Yes, it's what i ask : are you OK for a PR . And if yes, with what inside.

Currently :

1. filename_kkk.lss : can not be done without hard workaround (must replace all action)
2. Limesurvey logo and icon : OK in admin template, can be done in user template
3. Limesurvey string in Tutorial : ? Must disable tutorial in DB
4. Limesurvey link : ? Javascript can do it, but maybe it's best in Admin theme (see the config.xml proposition)
5. Review if coretemplatedir can be set or not (it's OK in 2.6, unsure since 2.50)

Personnaly : i think it must be done only for non super admin : then in Admin theme it's seems OK.
If you think it must be only the "server admin" system : the all in config.php

Yes, no problem, you can do this feature request to PR in develop.
You can implement as many settings as you like, because any setting would be very useful.

Whenever is possible, it is best to have settings in config.php.
If something is different per survey, then setting should be part of survey settings.
If it is theme related, it should go to theme config.xml.

I am okay with settings that hides the LimeSurvey name/logo. I am not okay with settings that change the LimeSurvey name/logo to something else.

@dominikvitt: I disagree with 'Any setting would be useful'. Settings have to be thought over thoroughly, especially long-term effects of implementing something new.

@c_schmitz : then Only file name export + limesurvey_links_show to TRUE

Like i said : other can be done in JS theme, and i think it's more related to Theme (except for the Tutorial). Then only export file name in config.php is OK for me :)

sounds fine.
