Include/offer a 4min 59sec refresh timer

[erik-jan-climate]

Since the EU forces all banking session to end after exact 5min:00seconds, the max fitting keep-alive interval your browser add-on offers is 4min. Yet, using 4minutes means loosing about 20% time for typing text and numbers into all kind of fields of a bank form (or looking up numbers that one need to fill their forms). Even 5minutes is already a very short amount of time, if one has to lookup account numbers, formulate concise text references, etc.

Thus, I kindly ask to include a reload timer allowing setting minutes plus some seconds.
If you are afraid of server overloads, you could restrict it in a way that a minimum interval has to be always 60 seconds (1min.) so that people do not run a 1sec keep alive script.

Alternative:
If allowing setting seconds cause huge re-coding/extra work to you, could you simply offer a switch/checkbox that can turn on a predefined foreground timer reloading the foreground page every 4minutes and 58seconds? This would do the job as well.

(by the way, I never got this background keep alive working in any kind of my sessions of different accounts... Which servers allow keeping sessions alive with background refreshes only? I am just curious. My bank sessions and other governmental sessions all ignore background reloads)
