Feature Request: script, address bar, app memory.

[f-ckAndroid]

i have some issues

• issue 1:
  there are no any a button or menu item to trigger a concrete script, all scripts have to run once when pages are loaded,
  XBrowser is an app allowing i trigger randomly any script by menus, why does Via browser have not this feature?
  why don't we reuse the address bar as a shell and replace the go button with a menu having items
  go/stop
  reload page
  eval
  invoke script
  …

• issue 2:
  the "clear data" feature does not work effectively, in app details it still has so much garbage data, i can't clear them, my app cost 1gb.

• issue 3:
  the address bar can extend, but it deny multi-line text, i can't type the enter key,
  before, i often use address bar as a tmp notepad, but now i can't.

• some other tiny issues, you may not care:
  i also care about the issue "Scripts ordering Scripts ordering #1148".
  scripts run twice when a page is started for mode "@run-at document-start".
  if I accidentally swipe a tab then it is removed without a confirm dialog.
