[Feature Request] Keep filter value active between device edits

[pavleec]

Hi,

I think that it would be realy helpfull and handy to change default behaviour of filter field to keep it's value active when moving through device settings pages. With houndreds of devices it would be realy usefull to limit them by name filtering, edit some settings and keep filter value still active without the need of entering it manually once again after returning to the SNMP Devices page. What do you think about it?
