ফেব্রুয়ারি / 24/2017 আপডেট করুন : সূচকের কাছে এখন ওয়েব লিঙ্কগুলি পিন করার বিকল্প রয়েছে
ভূমিকা
দ্রষ্টব্য: এই উত্তরের পূর্ববর্তী সংস্করণটি সম্পাদনা ইতিহাসের অধীনে পাওয়া যাবে, ভেবেছিলাম এটি আর প্রাসঙ্গিক নয়।
নীচে উপস্থাপিত সূচকটি একটি ভিন্ন প্রশ্নের জন্য তৈরি করা হয়েছে, তবে যেহেতু সুযোগটি নিজে উপস্থাপিত হয়েছে, তাই আমি এখানে এটি প্রকাশ করার সিদ্ধান্ত নিয়েছি। ফাইল ইন্ডিকেটর ব্যবহারকারীর ফাইল এবং ফোল্ডার অ্যাক্সেসের জন্য সহজ সূচক। এটি সম্প্রতি ব্যবহৃত ফাইলগুলি, বুকমার্কিং ফাইল এবং ডিরেক্টরিগুলি পরীক্ষা করার অনুমতি দেয়। বিশেষত, স্থান মেনু এই প্রশ্নের সাথে বিশেষভাবে প্রাসঙ্গিক।
আপনি যেমন স্ক্রিনশট থেকে দেখতে পাচ্ছেন, সূচকটি ইংরাজী ছাড়াও অন্যান্য লোকেলগুলিকে সমর্থন করে, সুতরাং আপনার সিস্টেমটি যদি ইংরাজী ব্যতীত অন্য কিছু ব্যবহার করে তবে এটি কার্যকর হবে।
আপডেট : সূচক এখন পিন করা হয়েছে .ডেস্কটপ ফাইলগুলি চালু করতে সমর্থন করে। উদাহরণস্বরূপ আপনার যদি ফায়ারফক্স.ডেস্কটপ পিন করা থাকে তবে এটি ফায়ারফক্স চালু করবে। সুতরাং, সূচকটি প্রোগ্রামগুলির জন্য দ্রুত প্রবর্তক হিসাবে ব্যবহৃত হতে পারে। বৈশিষ্ট্যটি লেখার সময় পিপিএতে যাওয়ার পথে রয়েছে (নভেম্বর 19, সন্ধ্যা 7:53 GMT, প্রক্রিয়াজাতকরণের জন্য প্রায় 24 ঘন্টা সময় নিতে হবে), তবে আপডেটেড সোর্স কোডে ইতিমধ্যে গিথুব এবং এখানে রয়েছে।
সূচক প্রাপ্ত
সূচকটি আমার ব্যক্তিগত পিপিএ পাশাপাশি গিটহাব থেকে পাওয়া যায় । এটি পেতে নিম্নলিখিত পদক্ষেপগুলি ব্যবহার করুন:
