Some graphical improvements

[serrq]

• the arrows can be removed in my opinion: just tap once to open and close the tab

• might you adding a single letter symbol to represent "morning", "noon", "afternoon", "evening"?

• might you turning dark also the top of the screen (in the dark mode)? The white roof I mean.

• possibility to manage the bottom tabs (adding, removing, changing position of each tab)

• might you adding the true black theme?

I think the arrows are reasonable to indicate the option to expand the cards.

• might you adding a single letter symbol to represent "morning", "noon", "afternoon", "evening"?

This is a very special request and i think it would confuse the users. And the actual due date is just one click apart.

• might you turning dark also the top of the screen (in the dark mode)? The white roof I mean.

I actually like to keep it. But if more people vote to change that i would do it.

• possibility to manage the bottom tabs (adding, removing, changing position of each tab)

I don't see that users need this high-gradual flexibility. But if a few more users vote for that i could imagine a settings preference to switch the order.

• might you adding the true black theme?

I would review a PR for that.
