I suggest to simplify the layout by putting all the submenus on the front of the tool. I mean on the first page. Put them in sequence. In this way most of the things will be visible on front page and we could make changes directly without clinking menu and then sub menu and sub sub menus etc. So days, teachers names, subject names, rooms, all are visible on the one place.
That is much too much text on a single screen. Don't forget that some guys work with an 13" display and 1366 x 768 Pixels only.
Thank you for your suggestion! I'll add it in the TODO.
Yes, as Volker said, it is very much information for a single page. Also, I don't have experience designing interfaces. I have a very sober style of working (I mean simple and efficient, without too many colors).
Also, I need to mention the lack of financial support. We are volunteers, and at least for me life is hard (I work only on FET).
If we can have so many menu buttons and tools on excel and ms word etc on a single screen then I think we can have at least that much buttons on a single screen of FET. It would not make a clutter but make it easier. E.g. we can have a table like structure with first column having like days, second column with teacher names, third column with subjects. So at least these three things can appear on one screen. Also we are thankful for the free of cost efforts of the FET team without financial support. We appreciate your work. Thanks
I will write down this suggestion. Thank you!
