Adresár

Adresár slúži ako jednoduchá, no šikovná náhrada známeho Address Book-a aplikácie Outlook Express. Design Adresara je veľmi konfortný a ovládanie je jednoduché. Databáza uchováva názovy osôb alebo firiem, e-mail, adresu web stránky, telefónne číslo, fax, číslo mobilného telefónu. Ďalej adresu a poznámky. Vyhľadávať je umožnené podľa mena, e-mailu, prezývky a poznámky. Ku každému záznamu prislúchajú malé informačné ikony, ktoré určujú aké záznamy sú pre danú osobu alebo firmu uložené v databáze. Vylepšením od klasického Address Book-a je bublinková informácia, ktorá po zastavní kurzoru myši na názve osoby alebo firmy zobrazí údaje ako číslo telefóna, e-mail a číslo mobila.

CD Drive

CD Drive je malá 50kB aplikácia, ktorá slúži na otvorenie a zatvorenie CD-ROM mechaniky. Inštalácia vytvorí na ploche dvoch zástupcov, ktorí majú rozdielne ikony. Jeden otvára a druhý zatvára mechaniku.

Podobná utilita a článok je uverejnený na stránkach The Code Project pod Open or Close CD-ROM drive.
