I'm currently designing a screen for mobile with a navigation bar and a filter button, however I'm at a loss about where is the best place for the filter button. This is my current screen
However I don't think the button is accesible enough, as the user might tap the menu button accidentally due to proximity. Another issue is if I should show the current filters on the table screen, or just show the current state on the filter's pop-up window? In case I should, where is the best place for the current filter information?
