I've reverted to the original version for more utility. The progress bar was added for mobile users since calculations might take longer than desktop but it kept from simple editing of planets.
To use, select the planet from the drop down list and click on the sign to place it. To change the sign for the selected planet just click on the new sign. To remove the planet from the chart click on the trash can icon. Ketu is automatically added opposite Rahu. Search is good for dates from years 1900 to 2100. Only for finding the planets not the ascendant.
