  • Professional, beautiful, elegant, and reliable. For me this is one of the simple reminders of the boon of computers--and one of my favorite programs for Linux.

  • I really like the Artha on my linux desktop. I would like to suggest two new features. 1. Selecting a word and poping up the meaning without manually select the word with mouse right-click. i.e similar to wordweb's ctrl+rightclick, fetches the meaning of the word, under the mouse cursor. It is not always easy to select the word if that word is part of a URL in browser or in a pdf ( todo in pdf we have to change the mode of selection from browse to text first and then select ) ctrl+rightclick or selecting word under mouse cursor is extremely fast and easier. 2. Dropdown suggestions as we start typing the word with from first letter or after few defined number of letters. Thanks for creator for a lovely great product.
