<p>This relates to basic Geany capability, not a plugin.</p>
<p>To have symbols recognised they need to be recognised by the ctags parser, but I doubt it considers an include a symbol, its not a name in the program.</p>
<p>You would have to modify the ctags parser to do it, note its a separate project from Geany <a href="https://github.com/universal-ctags/ctags">here</a>.</p>
<p>Making an include symbol clickable to open the file would then be functionality added in Geany, but somebodys gotta code it.</p>
<p>You are aware that in the edit window you can select the include filename and ++o to open it as a workaround?</p>
