Hello,

You can manage many things like this by creating you own custom theme pack!

So first download the one on which you want to base your own theme pack : icagenda.joomlic.com/resources/theme-packs

Then, unzip the archive.
In all files, replace the name of the theme pack by your name.
For example, replace all accurences of "ic_rounded" by "my_theme" in files/folder name, and inside files.

You can zip the folder again, and install it using the iCagenda Theme Pack manager (in iCagenda component) and see if this one installed correctly.

You can modify each php file. When you want to move a part of the content, just copy/paste it where you want it.
You can change too all the HTML structure.

Some "outdated" tutorial videos could eventually help you : icagenda.joomlic.com/docs/documentation/...our-first-theme-pack

Hope this helps to start with ?

Best Regards,
Cyril
