Thanks for reaching out and reporting these things, Victor.
When it comes to any sort of conflict or issue with The Events Calendar and its translations, feel free to post in The Events Calendar support forums here for assistance on those: http://wordpress.org/plugins/the-events-calendar
As for the feature ideas, these are all great ideas. You should submit them to our UserVoice page here: http://tribe.uservoice.com
↑ Users can “vote” on ideas on this page, and so if you submit ideas there and other people vote on them, it’s a possibility they could end up in our plugins!
We also unfortunately do not provide support in any language other than English — we do sometimes provide it in Spanish and French as well, but English is the only language we can guarantee communication in.
I will close this thread for now to facilitate the above things.
See you in the free forums and on our UserVoice! 😀
