Caractéristiques du navigateur Opera
Petite Taille
Opera pèse moins de la moitié de la taille de la plupart des navigateurs majeurs et pourttant il embarque un grand nombre de fonctions utiles et inovantes.
Sessions
Interface en multifenêtrage intégrée directement à l'interface principale permettant de gérer plusieurs sessions simultanées, la notion de session étant celle d'un groupe de fenêtres ouvertes sur un ou plusieurs sites et pouvant être sauvegardées, fermées, puis rouvertes toutes ensembles y compris durant d'autres sessions.
Interface Multi-Documents
Opéra est, par défaut, une application multi-documents, montrant des pages multiples dans la même fenêtre d'application et vous permettant de redimensionner et juxtaposer les pages. Cependant, Opéra peut également fonctionner en interface mono-document, en application tabulée, ou dans une combinaison d’interfaces de documents multiples et simples, lors d’utilisations en instances multiples dans de multiples fenêtres en même temps.
Changement de client de navigation et de messagerie.
Le passage de votre client de navigation actuel (Internet Explorer...) à Opera et de votre client de messagerie habituel (OutLook Express...) à Opera est facilité par la capacité d'importer les signets (favoris) et les messages vers Opera.
The Wand
