Keeping the feedback in mind, here is the improved version of Showtime now.
Showtime v1.2 has the following updates now

• Current Mode :: this modes show the tv channel listings for all selected channels running currently ( current time +/- 1hr )
  So now you have 3 modes to use the app
  • daily mode
  • search mode
  • current mode
• You can select as many channels you want and hit the GO button just once to get all the data.
  Seems like many users wanted this option as they didnt want to click on GO for each channel seperately . Pls note there will be an obvious time lag as now we will be reading mutliple xmltv files and not just one. Ive added a progress indicator to help know the progress.
  
• fixed the issue of special characters being blocked out for sweden,poland, netherlands and some other regions.
  
• some other minor updates, like typos, programme end time offset for UK, etc.

Screenshots are here

Note::all your settings and files will be removed in this update due to the enhancements. However for future minor versions this wont happen.

Some effort has been made to make a lovely colorful user guide (attached) , please please go through it before using the software. If you still have questions or need clarifications I'm happy to answer/clarify them here.

Thanks to all those who gave feedback and tested/voted for this app, but the more the better so we will have even more coming forward to test/vote.so keep the votes coming please

Finally special thanks to all the people who appreciated the effort and made a donation towards the project.
